20 Things You Didn't Know About Christopher Nolan
9. Tenet Will Be Michael Caine's Eighth Consecutive Nolan Film
Nolan has collaborated with no single person, whether cast or crew, more than Michael Caine, who with his appearance in Tenet will have made eight consecutive appearances in Nolan's films, starting with Batman Begins.
Though the size of these roles has varied wildly - in Dunkirk he showed up for a mere voiceover cameo - Nolan has dubbed the acting vet his "good luck charm," and of his decision to find a part for him no matter the size, he said, "It's Michael. He has to be in all my films, after all."
