There are only a handful of YouTube stars who have made the switch to television and film, names including EpicMealTime's Harley Morenstein, singer Troye Sivan and comedian Bo Burnham.

Australian YouTuber MyChonny, real name John Luc, is the latest to make the switch. The YouTuber has 2.3 million subscribers globally, and unlike many who've made the jump before him — he's not playing a bit part or an extra in a movie.

He is also doing his bit to challenge Australia's well-known lack of cultural diversity in film, TV and theatre.

Luc plays the lead character, Lawrence, in the Australian film Sucker, an adaptation of a stage show by Australian comedian Lawrence Leung, who also co-wrote the feature film. It's loosely based on Leung's years as a teenager.

The film tells the story of 18-year-old Lawrence, who is caught cheating on his final year math exam, failing to get into medical school and banished to stay at his weird uncle's house for the summer. By chance he meets "The Professor," a veteran conman who invites Lawrence to come alongside his daughter Sarah on a road trip, swindling "suckers" along the way.

Luc, who hasn't had any formal acting training or experience, was first approached via a YouTube private message from renowned television producer Robyn Kershaw, who is behind Australian films Looking For Alibrandi, Brand Nue Dae, as well as hit television series Kath and Kim.

Kershaw was looking to produce the film Sucker and asked Luc to audition for the lead role. It took four more years for the film to hit screens.

Within the monocultural landscape of Australian film and television, Luc, who is of Vietnamese and Chinese background — is clearly an anomaly. He told Mashable Australia the time it took to make and sell the film is due, in part, to the diversity of the cast.

"The film itself took 10-12 years to make, and they could've sold the film a long time ago but people wanted a white face for the lead. It's just things like that, we just have to push through it," he said.

It's actually taken 14 years for Sucker to be adapted from its original stage show at the Melbourne Fringe Festival to a film, according to the writer, Leung. "It might be the right time in Australia for there to be a lead in an Australian film which is an Asian voice and a face," he told Fairfax Media in Nov. 2015.

Luc agreed, stating it is a really big step for Asians who want to make it in the entertainment industry.

"Being Asian on screen, in a lead role, is just amazing, extraordinary. It gives a lot of hope to my fans out there, you know. That they can get into a movie like that," Luc said. "They just give up really easily, because they don't see any other aspiring Asian entertainers out there making it in Australia — because it's so hard."

Making the transition from improvisational pieces and rants on YouTube, to the demands of a script and a director in a film was a lot easier than he thought it was going to be, Luc said. His appearances at live shows, comedy festivals helped him prepare, aiding his on-stage presence.

Following Sucker, Luc is looking to America as his next stage, but in the meantime he still has unfinished business in Australia. "I'm focusing more on my comedy and YouTube content, and working on a new sketch series called The Chinaboy Show, with a stand-up comedian," he said.

"I wouldn't mind in the future, doing a movie that I write," Luc said. "A bit more MyChonny comedy, rather than playing an actor in somebody else's film."

Deep down, Luc looks up to his comedy heroes, hoping someday their paths will cross. "I wouldn't mind working with Jackie Chan one day, even if he's stopped doing all his Kung-Fu stuff," Luc laughs.
