I've done roles before where I've wanted to be buff and sort of fit or whatever. And I like to try and be a little bit fit because there's usually one scene in a movie where you've got to run, which means you've got to run for about five hours nonstop. So, for me, it's just worthwhile being fit because doing a movie can be kind of grueling for six, seven, eight weeks. Or 12 weeks.
