10 Famous Movie Scenes Only Made Possible By Deceiving Actors

10. Extras Had No Clue What Was Coming Next - Goodfellas

Few scenes became as instantly quotable upon Goodfellas' release as this gripping, dimly lit back-and-forth between the outstanding Ray Liotta and Joe Pesci did back in Martin Scorsese's 1990 crime epic.

Going down within the iconic Copacabana Club, Liotta's Henry is treated to a deliciously explicit and animated tale from Pesci's Tommy, only to find himself instantly put on the back-foot on the back of innocently stating that DeVito is "funny". Flipping the mood with masterful execution, Pesci flirts from friendly pal to menacing entity in a heartbeat and it was enough to leave just about everyone on-set feeling a little intimidated. More specifically, the extras sat around Liotta and Pesci who hadn't actually been told how the scene was expected to play out.

With Pesci largely improvisation this story and exchange, the look of genuine fear on those around him as he prods Henry with his now-legendary "Funny how?" delivery is about as real as it gets. The director's decision to hold back this vital information from his background artists ultimately paid dividends and added that bit more weight to a moment that once looked to be heading south very quickly.
