Fame has a funny way of finding people. Some actors spent years auditioning before getting noticed. Others were simply in the right place when destiny decided to tap them on the shoulder unexpectedly.

His acting was so memorable that it led to the spin-off series Mork & Mindy (1978–1982), which catapulted him to national stardom. Williams went on to have a prolific career in both comedy and drama, starring in movies such as Good Morning, Vietnam and Dead Poets Society.

Williams started performing stand-up comedy in San Francisco and Los Angeles, quickly gaining a reputation for his frenetic energy and originality. After seeing him perform in nightclubs, Garry Marshall selected him for television, giving him the alien Mork character in a segment of Happy Days.

She began by filming a controversial Burger King commercial that would actually land McDonald's and Burger King in court over comparative advertising claims. That spontaneous casting led to her amazing role as Kendall Hart on All My Children and then as the unforgettable Buffy Summers.

Child stardom wasn't on any family agenda until four-year-old Sarah Michelle Gellar was simply enjoying dinner with her parents at a Manhattan restaurant in 1981. The family was having a quiet meal when a talent agent approached their table, thrilled by the little girl's expressive personality.

Apparently, director Mike Nichols was desperately searching for someone to play Benjamin Braddock in The Graduate. Once Hoffman auditioned, Nichols recognized that his neurotic energy and everyman appearance were exactly what the character needed. What he felt was a "failed" audition earned him multiple Oscars.

Rejection defined Dustin Hoffman's early career. At 5'6" with unconventional looks and a nasal voice, every acting teacher, agent, and casting director told him the same thing: he'd never be a leading man in Hollywood. By the mid-1960s, Hoffman was working as an attendant in a psychiatric hospital.

Here, he became fascinated by the acting students and, driven by curiosity, decided to audition for the acting program. He was accepted, and this decision set him on the path to becoming an actor. As DeVito himself described, “I went in for makeup and came out an actor”.

At 4'10" with a distinctive appearance caused by multiple epiphyseal dysplasia, DeVito seemed like someone meant for a life behind the scenes until he took admission in the American Academy of Dramatic Arts. He had planned to become a makeup artist or set designer.

Her first roles were small parts in low-budget films, but she reached her peak when director Antoine Fuqua cast her in Training Day opposite Denzel Washington. Mendes later mentioned that she had actually decided to quit acting because of growing self-doubt.

Eva Mendes was just being a good friend when she agreed to help her neighbor with his photography portfolio. The aspiring photographer needed a model for practice shots, and Mendes figured she'd help out. Those casual portfolio photos ended up in the hands of a talent agent.

That’s when Blomkamp remembered Copley's glowing charisma from their working relationship and cast his former boss in the lead role. The movie's success was seen at Cannes, plus it bagged an Oscar nomination for Best Picture. He then got a major role in The A-Team (2010).

By his mid-twenties, Sharlto Copley had co-founded multiple companies and had become the country's youngest television producer. Copley's life changed when he hired a teenage Neill Blomkamp as a computer graphics designer at his production company. Years later, Blomkamp got the opportunity to direct District 9.

After Saturday Night Live was launched in 1975, his connections got him auditions, leading to his iconic position as the first Weekend Update anchor. That unplanned career made him one of the most recognizable faces of the 1980s through films like National Lampoon's Vacation and Fletch.

The privileged Woodstock native had graduated from Bard College and was working as a writer and editor at various magazines in the early 1970s. Apparently, his comedy breakthrough occurred almost by accident when he started hanging around an underground comedy troupe called Channel One.

Well, Theater director Bob LeMond cast young Travolta in a small role. That summer theater gig led to his move to New York at 16, then his well-known role as Vinnie Barbarino in Welcome Back, Kotter. The rest became cultural history with Saturday Night Fever and Grease.

Everything changed when army photographer David Conover arrived in 1944 to shoot propaganda photos of the women involved. Norma Jeane's natural photogenic quality struck Conover. She soon became a symbol of glamour and resilience, starring in classics like Gentlemen Prefer Blondes.

Factory work during World War II was supposed to be temporary for little Norma Jeane Dougherty. She was just trying to contribute to the battle effort while her merchant marine husband was deployed overseas, assembling parachutes and radio equipment at the Radioplane Munitions Factory in Burbank.

She was charmed by his ability to make her entire table laugh while describing the menu, so much so that she cast him in the horror film Cursed Part 3. That genuine personality would later make him perfect for a lovable character in Parks and Recreation.

The 19-year-old had dropped out of community college and was living in a van on the beach, working as a server at the Bubba Gump Shrimp Company. Actress and director Rae Dawn Chong was dining at the restaurant when Pratt's goofiness and improvisational skills caught her attention.

Miller took one look at Gibson’s battered appearance and told him to come back in three weeks to audition for the villain, Toecutter. When Gibson returned, his movie-star looks had healed completely, prompting the individual to cast him as the hero instead.

In 1979, Gibson accompanied his friend Steve Bisley to the audition because Bisley needed a ride to the casting call for Miller's post-apocalyptic thriller. An interview by SlashFilm tells us that the previous night, the actor had gotten into a fight that left his face swollen and bruised.

Trejo's evolution began in 1985. A fellow twelve-stepper called him to help on the Runaway Train set. Trejo thought he'd be doing community service; instead, a screenwriter who'd served time with him in San Quentin remembered his boxing skills and hired him to train actor Eric Roberts.

She began screaming and crying, creating a dramatic scene. Talent agent John Crosby, waiting in line behind her, was so mesmerized by her raw emotional power that he handed her his business card. That bank tantrum eventually led to her incredible role in The Devil's Advocate.

Bank tellers deal with angry customers every day, but they rarely witness Oscar-worthy performances. In 1994, 19-year-old South African model Charlize Theron's mother's check from overseas got held up by banking red tape. The Wells Fargo teller's refusal to cash her out-of-state check triggered a complete meltdown.

Then, 15-year-old Rosario Dawson decided to sit on her Lower East Side stoop to people-watch. Clark and screenwriter Harmony Korine were literally walking past her building when they spotted her street-smart energy. Clark approached her on the spot and eventually selected her for the film.

Larry Clark was facing the worst casting session of his career. The director had spent months searching for a teenage girl who could authentically depict the gritty urban youth at the center of his controversial film, Kids, but every audition felt fake and over-rehearsed.

William R Wilkerson, founder of The Hollywood Reporter, was conducting business at the cafe when something about Turner's confident walk and natural screen presence convinced him to take a chance. Within months, she was starring in They Won't Forget.

MGM's publicity machine would later claim that Lana Turner was "discovered" sipping a soda at Schwab's Pharmacy, but the truth is more mundane. The 16-year-old was actually at the Top Hat Cafe on Sunset Boulevard, ditching typing class at Hollywood High School to grab a Coca-Cola.

A photographer from i-D magazine was attracted to Sevigny's authentic punk aesthetic. Well, she never wanted to be mainstream, even after that first photoshoot led to modeling opportunities. However, when Harmony Korine saw her in Kids, he was shocked by how she personified genuine youth rebellion.

Picture the coolest teenager you've ever seen: baggy jeans, vintage band t-shirt, skateboard under one arm. That was 17-year-old Chloe Sevigny cruising through Manhattan's East Village in 1993, completely oblivious to the fact that her effortless style was about to make her famous.

Desperate for income, Morrison took a summer job in 1926 at Fox Film Corporation as part of the “swing gang”. These were basically manual laborers who moved props. Walsh became Morrison's mentor, eventually giving him the stage name "John Wayne” for The Big Trail.

The irony of John Wayne's career is that America's ultimate cowboy was a college boy from Iowa who got his start moving furniture. Born Marion Morrison, he was studying pre-law at USC on a football scholarship. Unfortunately, or fortunately, a shoulder injury ended his athletic dreams.

This neighbor happened to be friends with Buffy the Vampire Slayer writer Marti Noxon, who was complaining about their casting nightmare: finding someone impossibly handsome to play Angel. The neighbor immediately thought of “that gorgeous guy who walks his dog past my house”.

Forget about acting classes or headshots. This man’s big break happened because his neighbor was a gossip. The struggling actor was walking his dog in his Hollywood neighborhood. Suddenly, a lady who lived nearby noticed his striking good looks and brooding demeanor.

Aniston's vulnerability in that moment was born from genuine desperation. By the way, Aniston almost didn't get Rachel—she originally auditioned for Monica. The writers were so impressed by her comedic timing during callbacks that they tailored Rachel's character to match her strengths.

Warren Littlefield was just trying to buy gas. The NBC Entertainment president had no idea that a struggling actress would approach him at a Sunset Boulevard station and ask the question that would change television history: "Will it ever happen for me?"

One day, while working as a carpenter, Ford was recommended for an audition by Fred Roos. The filmmaker was immediately struck by his natural authenticity and dry wit during their work conversations. This casual relationship led Lucas to cast him in American Graffiti.

What's remarkable about Harrison Ford isn't just that he was discovered while doing carpentry. It's that he had completely written off his acting career as hopeless. After struggling with minor roles in the late 1960s, Ford decided Hollywood wasn't for him.

However, his natural athleticism and working-class charm eventually clicked. Years later, when he pitched Magic Mike to Hollywood, studio executives were skeptical about a stripper movie until Tatum explained it was autobiographical. The film collected a whopping $167 million, making it a global success.

After losing his college football scholarship dreams at Glenville State, Tatum was left lost about his future. Luckily, a talent scout spotted him randomly walking through Miami's South Beach. The actor had described himself as "a nobody" when starting out.

Director Wes Craven spotted something special in the reluctant tag-along. Interestingly, it was Craven's daughter who sealed the deal. She found Depp "dreamy" and convinced her father to cast him. Depp later admitted that he had only agreed to take the role to pay his rent.

Music was Johnny Depp's religion. He'd moved to Los Angeles in the early 1980s with his band The Kids, determined to make it as a rock star, not an actor. It all changed when friend Jackie Earle Haley dragged Depp to his audition for Nightmare on Elm Street.
