Lilly Singh on Getting 'Vulnerable' in 'A Trip to Unicorn Island,' and Her Next Move: 'Casual World Domination

The YouTube star opens up to ET about the scary experience of giving up control in her documentary.

Lilly Singh wants you to take a trip to Unicorn Island. No, seriously.

ET caught up with the YouTube star at the premiere of her new documentary, A Trip to Unicorn Island, at the world-famous TCL Chinese Theatre in Hollywood on Wednesday night.

“My body is not ready, my brain is not ready, no part of me is ready,” Singh gushed to ET. “This is amazing!

The movie, named after Singh's personal (and fictional) “happy place,” chronicles the 27-year-old’s 2015 world tour and her rise to Internet superstardom. It’s the first time she’s given fans an all-access pass to her personal life, including her battle with depression.

“It was a really different experience, because when I make videos on my own channel, I’m very much in control of what I put out there,” Singh said, “how I edit it, what I shoot, and this is a situation where I literally gave other people a camera and said, ‘You can shoot whatever you want.’ So you really get an inside look into a lot of stuff you’ve never seen on my channel.”

Singh handed over control to director Scott Winn, a fellow YouTuber.

“When I first met Lilly, the fact that I knew nothing about her and wasn’t a fan, and that completely changed in less than 24 hours? I was like, OK, something’s going on with this girl, and I’ve got to figure out what is it,” Winn told ET.

“I got to know her a little bit and found out, this girl is inspiring,” Winn added. “She’s a hard worker. I mean, the things she is accomplishing, and her message alone was something that really resonated with me.”

The documentary is now streaming on YouTube’s new subscription-based platform, YouTube Red -- and Singh said the response is already overwhelming.

“So many crying face emojis!” Singh said of the tweets she’d received so far from her viewers. “All the crying face emojis! I think people are really liking it … You really see a different, a different side of me that I think is really, really genuine, and vulnerable and raw.”

The movie’s L.A. premiere brought out big digital stars, including Tyler Oakley, Hannah Hart, Colleen (Ballinger) Evans and Joey Graceffa, along with Singh’s parents, Malwinder and Sukhwinder, who were beaming on the red carpet.

“For her, this is a dream come true,” Singh’s parents jointly exclaimed to ET.

“I feel like the luckiest girl on the planet,” Singh said of celebrating with her family. “Truly.”

Of course, we had to know: How does one top a movie premiere at the Chinese Theatre?

“I mean, casual world domination is on the to-do list,” Singh joked. “I’m just so thrilled with the turnout of this movie, I want to embrace this moment for as long as I can.”
