20 celebrities who were discovered in the most unconventional ways

Harrison Ford wasn't even auditioning for Star Wars ; he was just a working carpenter installing a door for George Lucas. Lucas asked him to read lines with other actors as a favor, and he was so good they gave him the part of Han Solo, changing his life forever.

Sometimes, waiting tables actually pays off in Hollywood. Chris Pratt was living in a van and waiting tables at a Bubba Gump Shrimp Co. in Hawaii when he served actress Rae Dawn Chong, who cast him in his first movie on the spot.

A good old-fashioned public meltdown is what kick-started Charlize Theron's career. A talent agent discovered the future Oscar winner at a bank while she was passionately yelling at a teller who refused to cash her out-of-state check.

He was studying biochemical engineering in college, but Ashton Kutcher's real breakthrough happened at a bar, not in a lab. A modeling scout discovered him one night in Iowa City, which quickly led to a career-making role on That '70s Show.

We can thank Nicolas Cage for Johny Depp's entire career. Depp was tagging along with his friend, Jackie Earle Haley, to an audition when Cage spotted him and suggested he try acting, even helping him get his first agent.

Talk about a lucky lunch break. A nine-year-old Natalie Portman was just grabbing a slice of pizza after dance class when an agent from Revlon approached her, launching one of the most celebrated acting careers of a generation.

A jumbotron is responsible for discovering one of the most iconic bombshells of the '90s. Pamela Anderson was just a fan at a Canadian football game until her face was broadcast on the big screen, causing the crowd to go wild and a local brewery to offer her an endorsement deal on the spot.

Before he was a Hollywood heavyweight, Channing Tatum was a struggling roofer and male stripper. He was discovered completely by chance while walking down the street in Miami by a modeling scout, which eventually led to his breakout role in Step Up.

A family vacation to New York City turned into a career launchpad for a 14-year-old Jennifer Lawrence. A talent agent spotted her in Union Square and asked to take her picture, and the rest is Oscar-winning history.

Before he was Hollywood's go-to tough guy, Jason Statham was a real-life street vendor selling fake perfume and jewelry on the streets of London. Director Guy Ritchie needed an authentic character for Lock, Stock and Two Smoking Barrels and cast Statham to basically play a version of himself.

Mel Gibson didn't even want to be an actor at first; he was giving his friend a ride to an audition for Mad Max. He had gotten into a bar fight the night before and was covered in bruises, but the casting directors loved his rugged look and asked him to come back.

The Fresh Prince was born at a party. Will Smith was already a successful rapper, but Warner Bros. executive Benny Medina launched his acting career when they pitched him the idea for a sitcom based on his own life on the spot.

Sometimes, all you have to do is sit on your front porch. A 15-year-old Rosario Dawson was doing just that in her Lower East Side neighborhood when a photographer and a film director discovered her and cast her in the controversial 1995 film Kids.

The original "discovered on the internet" story belongs to Justin Bieber. His mom started posting videos of him singing R&B covers on YouTube, which were accidentally discovered by talent manager Scooter Braun, who immediately flew him out to meet Usher.

The now-defunct app Vine is responsible for launching Shawn Mendes' career. His six-second covers of famous songs gained a massive following, which caught the attention of a record label and turned him into a global superstar.

You never know who's listening. Toni Braxton was just singing to herself while pumping gas at a gas station when a record producer heard her incredible voice, handed her a business card, and ultimately signed her to her first record deal.

Ed Sheeran 's big break came thanks to the kindness of an A-lister. After relentlessly playing small gigs, he was invited to perform on Jamie Foxx's satellite radio show and was so impressive that Foxx let him crash on his couch for six weeks while he got his career off the ground.

Before he was a global icon, The Weeknd was an anonymous mystery. He uploaded a few dark, moody R&B tracks to YouTube under his now-famous moniker, and the songs generated so much organic buzz online that Drake posted them on his blog, launching his career.

A 14-year-old Gisele Bündchen was discovered by a modeling agent while eating at a McDonald's in São Paulo, Brazil, on a school trip, proving that everybody needs a Big Mac now and then. 

The legendary Kate Moss was discovered at just 14 years old while waiting for a flight home at JFK Airport in New York. A modeling agency founder spotted her unique look, and the era of "heroin chic" was unofficially born.
