This is not an exhaustive list, but rather a representation of the print and non-print sources helpful in looking for reviews, evaluations, and criticism of a particular film. Books listed are located in the Social Sciences and Humanities Library, Geisel Library, 2nd floor, in the SSH Reference stacks.
Before you start to search for criticism, it is a good idea to establish the date the film was released. It will make a difference if the film was released in 1930 or 1999 as to where you will find the information you need. A quick way to establish date and get some general information on the film is Internet Movie Database.
