Taxi Driver is about a deranged and mentally unstable cab driver named Travis Bickle who is a Vietnam vet that just cannot stand the crime in the streets and the horrible conditions he sees around him. It gets to him so much that he cannot sleep and to help him deal with his insomnia he takes a job driving a cab on the night shift where he gets to see the whole spectrum of what he calls “the scum of the streets.” He attempts to reach out and date a Senatorial campaign worker named Betsy but his chances at happiness with Betsy are derailed when he takes her to see a porno movie on their first date. To Travis it seems natural because he is around that sort of thing all the time but to Betsy it is horrifying and she leaves. Travis tries to apologize but Betsy wants nothing to do with him. Then Travis meets Iris, played by Jodie Foster, and Iris is a 12 year old hooker. Travis spends a lot of time trying to convince Iris to get off the streets and go back home but she refuses. In the end Travis decides that all that can be done is to take two high powered hand guns and go kill the Senator that Betsy works for.
Taxi Driver wound up with four Oscar nominations with one going to Jodie Foster and another going to Robert De Niro. It became extremely successful both financially and critically and is referred today as one of the most dangerous movies ever made. It also spawned one of the most famous movie catch phrases ever when Robert De Niro looked at himself in a mirror and asked “Are you talking to me?” which, as both De Niro and Scorsese would both later admit, was totally improvised by Robert De Niro.
