I saw this at 1 am Saturday on this TV out of Indianapolis and couldn't tape, tiVO or DVD it, so I stayed up to watch.
I liked the rough, LOW budget Corman style of this movie without the "composition and mannered shots" of the big budget Papillon with McQueen and Hoffman.
You could feel the roughness, smell, and atmosphere of being in prison in the middle of nowhere. The pig skinning was very realistic as was the language and full nudity.
This is not Camp Granada.
James Luisi goes on to become the constipated Lt. Doug Chapman in Rockford Files and Christopher George becomes an action cop on Hawaii five-O.
James Brown is the lead, but absent in the top of credits on IMDb, and Corman utilizes this low budget action star who was in many low budget films to interesting effect.
The guards, the brutality, the hopelessness... are all there in the French prison.
It almost feels like a documentary through the kinetic energy and cutting of the movie.
I really like Corman's attitude of "get 'er done" way before it became a catch phrase.
Enjoy.
