Depends on what type of film you're looking for.
Yeah, could you be a bit more specific?
But off the top of my head, my (highly biased) Film Studies Primer would include the following:
Metropolis (1927)
Battleship Potemkin (1925)
King Kong (1933)
La Grand Illusion (1937)
The Wizard of Oz (1939)
Pinocchio (1940)
Citizen Kane (1941)
Casablanca (1942)
The Big Sleep (1946)
Othello(1952)
Pather Panchali (1955)
Le Notti di Cabiria (1957)
A Bout de Souffle (1960)
Yojimbo (1961)
Lawrence of Arabia (1962)
Andrey Rublyov (1966)
Bonnie and Clyde (1967)
Aguirre: der Zorn Gottes (1972)
Chinatown (1974)
Monty Python and the Holy Grail (1975)
Taxi Driver (1976)
That's my fairly compact, if incomplete, history of film. Basically, if you're actually
studying film, you should have at least seen these. Like I said though, if you can be more specific about what you're looking for, I got like, a zillion more recommendations. But then, who doesn't?
