The 64-year-old actor - who plays the daredevil archaeologist - has been told the weapon will have to be computer generated because of new film safety rules.
But Harrison thinks the regulations are ridiculous and has reportedly said he'll pull out of the film if he can't wield his own whip.
I'm not sure which is sillier: a CGI whip or a 64-year-old action hero.
Part of me is excited about a new Indiana Jones movie and part of me wants Harry to pull out for the sake of his own dignity (and perhaps for the sake of the franchise).
