I've seen the whole the $treet series. It's got nothing to do with trading. all about drama in personal love lives.
There is also an excellent (Korean) trading movie called "The Scam", all the details here : http://en.wikipedia.org/wiki/The_Scam_(2009_film) (it is possible to find it with English subtitles, Google is your friend... wink wink )
Man with a Million (1954) "The Million Pound Note" (original title) http://www.simonprior.com/the-million-pound-note-1954/ http://www.mineweb.com/mineweb/content/en/mineweb-gold-analysis?oid=207314&sn=Detail
floored is a good if depressing movie about floor traders in chicago getting replaced by machines. The pit is another doc around the same time 2008-2010 that is available on netflix streaming. I haven't seen it.
not sure if anyone has listed this yet, but "Margin Call" for my money is the best movie about Trading. You can stream it on Netflix: http://en.wikipedia.org/wiki/Margin_Call_(film)
