12 Famous Actors Unbelievably Hidden In Huge Movies

1. Bill Murray - Dumb and Dumber To

Bill Murray's unannounced Zombieland cameo is now the stuff of actual legend, but it's so popular now that most film fans know of its existence. No matter how delightful it was to see when the film was released.

More fittingly hidden was his turn in the awful Dumb And Dumber To, in which he plays Ice Pick, the roommate of Jeff Daniels' loveable oaf Harry. He wears a yellow bio-hazard suit - made famous by Breaking Bad and actual scientists - and never actually shows his face, delivering one sarcasm-drenched line.

The ruse is pretty much the only successful bit of comedy in the entire movie.
