10 Times Actors Broke Character In Movies

Whoopi Goldberg may be a damn pro, but even she has her limits, and evidently couldn't resist losing it in front of the legendary Dame Maggie Smith while filming a scene in Sister Act.

When Reverend Mother (Smith) gives Deloris (Goldberg) a dressing-down for supposedly "corrupting" the church's choir with her unorthodox ways, there's a sudden knock at the door and a flummoxed Mother loudly shouts "Come in!" in what can best be described as a high-pitched grunt.

Given that Goldberg clearly wasn't expecting such a strange, loud sound to be expelled from Smith's vocal cords - and Smith probably wasn't either - she finds herself unable to keep fully in character, abruptly lifting her hand to her mouth as she tries to prevent herself from completely breaking.

Thankfully this came at the natural end of the shot before it cuts to the door opening, in turn ensuring that it was still usable and Smith's unexpected bleating wasn't forced to remain on the cutting room floor.
