Oct. 28 (UPI) -- Asa Butterfield says it doesn't feel extraordinary to have had a 20-year acting career by age 28. The animated film Stitch Head, in theaters Wednesday, allows him to play a kid again.

In a recent Zoom interview with UPI, Butterfield reflected on having a decades-long career history at such a young age. Still, Stitch Head is his first lead role as a voiceover artist in an animated film, aside from one episode of Thunderbirds Are Go.

"It's what I've been doing so it feels very normal to me, but to have a 20-year career at something at 28 is pretty unusual," Butterfield said. "Acting is one of the few careers where that's possible, but I feel pretty experienced. I feel like I know what I'm doing at this point."

Stitch Head is a creature assembled by a professor (Rob Brydon) from different parts. Stitch befriends the professor's latest creation, Creature (Joel Fry).

Butterfield embraced playing a character who may not even be technically human.
