Yep, the stars have truly aligned for this one! LEARN MORE.

Joe Locke Heartstopper Movie Tease

Joe Locke has had arguably one of the biggest young careers in recent years.

Joe’s very first acting projects have been Netflix’s Heartstopper, where he stars as Charlie Spring, and then he followed it up with Marvel’s Agatha All Along, playing Wanda Maximoff’s son, Billy.

So, to celebrate Agatha All Along, Heartstopper, his Broadway debut in Sweeney Todd, and so much more, we caught up with Joe to talk about everything in a game of First Times.

He recalled his first — of MANY — auditions for Marvel, with the first audition including reading the scene when Agatha (Kathryn Hahn) interrogates Billy in Episode 1.

Joe also revealed that a lot of Heartstopper is actually improvised, saying, “There’s a lot of montages and so, in the script it’ll just be like, ‘Nick and Charlie play in the snow.’ A lot of it is improv. I am not the best at improv. I’m great at improv if I’m, like, not being so nice to someone because it’s easier. But, like, Heartstopper improv is a lot of cushy, nice stuff, so Kit is far better at that than me, so he leads it often.”

And he even teased the upcoming Heartstopper movie, which will be the final installment. He told us, “It is grown up more. But it’s still Heartstopper. I think we’re trying to really make it [as] cinematic as possible and really finish the story in a really nice way.”

And heck, we even had time to ask some questions not related to Joe’s impeccable acting career so far, like who his first celebrity crush was.

And be sure to watch him in Agatha All Along and Heartstopper, with each streaming on Disney+ and Netflix now.
