As wonderful as a carefully crafted script is, some of the best movie moments are simply made up on the fly.  CineFix returns with another great movie list – Top 10: Improvised Scenes in Movie History.  Some directors hate improv and some barely require a formal script.  I think erring on the side of having a Nolan-esque literary script in place is probably the prudent route, but as those are a handful a year, there’s something seriously admirable about an actor/director collaboration that just spontaneously generates magic on the spot.  While improv is most associated with comedy, a good portion of the spots on the list go to famous dramatic scenes from Apocalypse Now, Goodfellas, A Clockwork Orange, and The Breakfast Club.  Improv is a staple of comedy, and a lot of your favorite comedy moments, be they from Judd Apatow, Bill Murray, or Chris Guest, also make the list.  Rather than picking a scene for #1 though, CineFix made the very wise choice of simply sticking Robin Williams’s name up top.  If you’re going to have a list heralding lack of structure, Robin deserves to sit atop it with his whole body of work.
