"The French Connection is the 1971 crime drama starring Gene Hackman as James "Popeye" Doyle, a relentless NYPD detective who is determined to take down the infamous drug trafficking ring. The film was directed by William Friedkin and was based on the actual cases investigated by Detective Eddie Egan, who co-stars in the film as another character. Hackman received an Academy Award for his portrayal of Doyle and the film is best remembered for its famous car chase with an elevated train."
I love this classic and own it on DVD. I have to drag it out every now and again.
