Here is a treasure trove of film available for cineastes everywhere.
http://www.archive.org/details/movies
This site contains feature length films as well as animated shorts, home movies, etc.
Here is a sample of some of the films on offer:
Panic In the Streets featuring Richard Widmark and Jack Palance (directed by Elia Kazan)
The Red House (1947) featuring Dame Judth Anderson and Edward G. Robinson
His Girl Friday (1940) featuring Cary Grant and Rosalind Russell
Dressed to Kill (1946) featuring Basil Rathbone as Sherlock Holmes
Night of the LivingDead (1968)
Reefer Madness
Nosferatu …. you get my point.
My suggestion would be to take some time and look at all the videos that are available. They are available for download and streaming.
Happy Viewing!
