Interesting, I’ve seen “Papillion” fo sho. I’ll have to watch it again, all I remember is them being in prison and he has calculated the rotations of the waves to escape, or something. I’ll look it up.
Papillon is a good movie, but the book is absolutely fantastic.
“Papillon is a memoir by convicted felon and fugitive Henri Charrière, first published in France in 1969. It became an instant bestseller. It was translated into English from the original French by June P. Wilson and Walter B. Michaels for a 1970 edition, and by author Patrick O’Brian. Soon afterward the book was adapted for a Hollywood film of the same name.”
