Jail Break (1961)

Certainly not one of Manfredi's best movie, it's the rather depressing story of four inmates who plan their escape in a way similar to "Shawshank Redemption" but with less glorified results.

Everything about the movie screams out "poverty" and the rather miserable life of the lower classes, from sordid environments (even the prison is a dump) to dreadful relationships.

There is some attempt at humor but it sorts of falls flat. However, the actors do a good job, as it was to be expected by real professionals.
