As the new Lion King movie continues to break records at the box office, here’s a fun fact from the original Lion King movie. The lions roaring in the original film weren’t lions at all. Real lions don’t actually have a very ferocious roar. So instead the movie makers used tiger roars in some scenes. But many of the best roars came from this guy, Frank Welker with the help of his trash can. Who’d have thunk it?
