My top 5 are:
Boiler Room (Persistance in selling)
Cocaine Cowboys (Vol. 3) (Distribution and preparation)
Pirates of Silicon Valley (Negotiating deals, Innovation and improving on your competitors work)
There Will be Blood (Keeping you cards close to your chest, being shrewd and watching who you trust)
Trading Places (Events shape the markets and connections can make a HUGE difference)
