10 Amazing Improvised Movie Moments

6. When Harry Met Sally - "I'll Have What She's Having"

http://www.youtube.com/watch?v=gj988bo2iKM Here's a classic scene that accompanies itself with one of cinema's best improvised moments, which acts as a cherry on top of what is an undeniably brilliant, erm, performance, from Meg Ryan. As Sally (Ryan) and Harry (Billy Crystal) are sitting in Katz's Delicatessen in Manhattan, the debate arises over whether men can tell if women are faking orgasms, and Sally then goes about proving her opinion that men cannot, by loudly faking one in the middle of the diner, much to the dismay of just about everyone in the place. A patron nearby - who happens to be played by Rob Reiner's mother - says to a waiter, "I'll have what she's having". Many will argue that Reiner's sweet old mum stole the scene away from Ryan. Unquestionably, it's one of those flash-in-the-pan moments that only comes along every so often.
