I think my favourite American film of all time is Dog Day Afternoon. Today I was sent a link to this art video by the French artist Pierre Huyghe, featuring the late John Wojtowicz (played by Al Pacino in the movie) in a renactment of the bank robbery. I don't know anything about the making of this, or about Huyghe, so I'll have to do a little research, but Wojtowicz is well worth listening to:
