'Stranger Things' Star Finn Wolfhard, 20, Is All Grown Up at Premiere for Directorial Debut

Finn Wolfhard is all grown up in new photos from the first showing of his latest project.

On Sept. 10, the 20-year-old attended the TIFF premiere of his directorial debut for teen horror flick Hell of a Summer, which he helmed alongside friend and Ghostbusters: Afterlife co-star Billy Bryk.

The Stranger Things star posed on the red carpet in a maroon blazer paired with a black t-shirt and dark pants, going for a business casual look. His hair was styled in his signature shag, which curled up right below his ears.

Wolfhard was kind enough to stop to sign autographs and snap selfies with fans while making his way down the red carpet. Afterwards, he took a group photo with the movie's cast and Bryk.

"I'd never written with someone else before. And that really unlocked something in terms of just speed and ease of writing, because I really have the tendency to beat myself up a lot during the writing process. Not even being negative about something, but just being too precious with it," explained Bryk.

Wolfhard shared that they had to think beyond what they'd consider to be funny and see how they could make it appealing enough for it to sell in Hollywood. "You have to subscribe to the machine of Hollywood in order to make a film. And that's the hard part, is introducing it to other eyes and a lot of people that don't necessarily understand it or whatever," he said.

He added, "When you're young, it's pretty…For any age, when you're giving your work to someone, it can be discouraging. That was the hard part, I think. But then it was amazing too."

As for what fans can expect from the movie, Bryk said, "This isn't your straight-up summer-camp slasher film, because as much as it does lean into some of the tropes, it also doesn't in a lot of other ways." He additionally noted that he and Wolfhard "really wanted to make, first and foremost, a team comedy that gets interrupted by a killer."
