It could very well be. I read the book the movie as based on and it was written by Henri Charriere AKA Papilon. He could have very well made up a lot of his story. He might have never been imprisoned on Devil’s Island. I also read his follow up book Banco.
I only saw Birdman of Alcatraz once, on network TV when I may or may not have reached puberty, but I liked it a lot. Also, the best POW was probably the Renoir.
Birdman of Alcatraz, I forgot about that one. I remember seeing it back in the day when NBC had Saturday Night at the Movies. Shit, that must have been 60 years ago. Burt Lancaster was always great.
Stalag 17 is one of my favorite movies of all time. I was in my 20’s when I found out it was based on a Broadway play (which diminished my love of the film not at all).
It takes place in a concentration camp, so not quite a prison or POW film, but “The Counterfeiters” is fantastic. It’s a fictionalized account of Operation Bernhard, the largest counterfeiting operation ever attempted (by the Nazis, no less). Highly recommend tracking it down if anyone hasn’t seen it yet.
