The actor will make his debut as Clark Kent and his superhero alter-ego in Supergirl this autumn (16), and he has already mastered the most difficult part of his role - getting changed.

"It's one of those things where you put it on, and it’s the nicest Halloween costume you’ve ever worn," the Teen Wolf star tells Entertainment Weekly. "Then, once you step on set, it becomes something different because people actually start addressing you as Superman.

"The first couple of times it definitely took longer to get into. I started to think that Superman’s greatest power was actually being able to just jump into it (the suit) as quickly as he does, because it’s not quite as smooth the first couple of times you do it.

"It’s kind of like putting on a wetsuit. I’ve introduced an old surfing trick, so if (I) put a plastic bag over my feet and hands when I put it on, that seems to cut down a little bit of time, so that’s been helpful in the process."

The new season of Supergirl will debut on TV in America next month (10Oct16).
