The Searchers, the classic western with John Wayne, directed by John Ford.
The Grapes of Wrath, another visually stunning John Ford picture, with cinematography by Gregg Toland.
Casablanca. Bogart and Bergman and "As time goes by".
The Blues Brothers. Some great music and the best car chase scenes ever filmed, save for Bullitt.
The French Connection has the absolute hairiest car chase in NYC that was real, OK real in a sense. They planned a lot of it and used off duty NYPD officers to stop traffic. They did not get the necessary permits and they did keep going through areas that were not controlled and did hit a guy's car that was not scripted. He had just left for work and got creamed and a new car. They left it in the film.
