Christopher Nolan confirmed in a conversation with NJ.com back in 2017, marking the seventh time the actor and director worked together (soon to be eight with Tenet).
Christopher Nolan loves using the same actors time and time again in his movies, and it’s no different in Dunkirk which features two of the director’s longtime featured players: Tom Hardy and Cillian Murphy.
Eagle eye, err eagle ear(?) members of the audience probably picked up on Caine’s distinct voice as the commander on the other end of Hardy’s radio throughout the early goings of the movie.
But two stars of The Dark Knight Rises and Inception aren’t the only ones to make an appearance in the 2017 war drama, as none other than Michael Caine makes a brief appearance (his voice anyway).
