2. 'Taxi Driver'
The back-to-back success of Mean Streets and Alice Doesn't Live Here Anymore meant that Martin Scorsese had the power to make pretty much whatever movie he wanted in 1976. The end product of that freedom was Taxi Driver, the tale of a disturbed New York cabbie that becomes infatuated with a woman working for a political candidate. The more she rebuffs his advances, the crazier he gets until he decides to take a drastic action. Along the way, he befriends a teenage prostitute played by Jodie Foster. Over the years, Scorsese and De Niro have talked about creating a sequel, but it seems unlikely that'll ever happen. That's probably a good thing. Some things are best left alone.
