Ol' Max certainly had a diverse career: A Knight in the Seventh Seal, Jesus in the Greatest Story Ever Told, Ming the Merciless in Flash Gordon, Some creepy guy in Hannah and her Sisters and Brewmeister Schmidt, among others.
And don't forget he played the assasin in 3 Days of the Condor. And he played a part in Dune (I think it was Liet-Kines).
