12 Famous Actors Unbelievably Hidden In Huge Movies

10. George Harrison - Monty Python's Life Of Brian

Given that The Beatles were "more popular than Jesus" at one point (in John Lennon's own delightfully provocative words), you'd have thought they'd be above bit-part cameos in quirky British comedies about the not-Messiah.

But not George Harrison, who showed his appreciation for iconic comedy troupe Monty Python by stepping in to help finance Christian-baiting comedy The Life Of Brian in 1979 with his own money. So enthusiastic was he about the project - which he set up a production company specifically for - that he also appeared very briefly in an uncredited role in one scene.

He blended in perfectly, but look hard enough and he's easy to spot.
