Director Ryan Coogler's Sinners is full of shocks and surprises, the last of which is a "Thank You" to director Christopher Nolan in its credits.

Ryan Coogler acknowledges Christopher Nolan in ‘Sinners’ end credits after receiving valuable advice on IMAX technology, making history as the first film to combine IMAX 65 and 70 mm cameras in a feature production.

The film represents a departure for the “Black Panther” director, and a creative risk; it grapples with ideas about music, race, family, religion—and vampires.
