9 Insane Times Movies Stupidly Hid Actors Behind Prosthetics

9. Idris Elba - Star Trek Beyond

If you're cast in a Star Trek movie, there's a good chance your performance is going to be wasted after being forced into some kind of alien costume. In fact, the most recent instalment in the franchise, Star Trek Beyond, took this to the next level with Idris Elba's alien warlord, Krall.

Though quite a menacing presence, Elba is entirely obscured by the prosthetics required to transform him into the villain. He's completely unrecognisable for the most part, and even some brilliantly intense eye acting couldn't quite detract from the fact that his ability to emote had been reduced massively by the bulky prosthetics weighing him down.

Fortunately Elba didn't spend all of his time wearing the makeup, and there actually is a cool little twist towards the end that sort of, maybe, justifies it. Still, there's no denying that the actor's best talents were mostly wasted by being caked in such a garish set of alien prosthetics.
