I watched Papillon the other day and it was a bit 'meh'.
I had just read the book, but remember the film being ace when I was younger.
On The Buses - used to love the TV and film versions - bit cringey now Butler!
They never made a follow up to Papillon but Henri charriere wrote a follow up book BANCO following his exploits after escaping Devils island , obviously not as good as Papillon but well worth a read
