Based on a (mostly) true story: Papillon was adapted from a memoir written by Charrière first released in France back in 1969

Reunites Sons of Anarchy (2008) co-stars Tommy Flanagan and Charlie Hunnam.

Papillon means 'Butterfly' and was Henri Charriere's nickname due to the butterfly tattoo on his chest.

There is a popular song based around someone remembering seeing the film with his father, called "Hey you Bastards, I'm still here!"
