Christopher Nolan is known for using technical wizardry to bring his films to life, and Tenet is no exception. The blockbuster uses the concept of "inversion" to show objects and people moving backward through time, as the eponymous Protagonist (John David Washington) races to stop an apocalypse.

Nolan was a recent guest on the ReelBlend podcast, where he discussed the technical aspects of the film. The use of IMAX 70mm cameras led to what Nolan says is his favorite shot in the entire film.

"One of my favorite shots in the film, which is a bit of a throwaway, is the shot looking down from the bow of the boat where you see the waves running backward… That was one where we were on this ice breaker, and we sort of thought, ‘Let’s try and get the camera out there somehow, and stick it to the side of the hull," Nolan said. "It was [laughs], it was a very complicated shot to get, but it’s things like that that I don’t think we would have dared to do with those cameras when we were starting out with them on The Dark Knight. Just, over time and experience, you wind up using it like you would any other format, and that really frees you up."

Written and directed by Christopher Nolan, Tenet stars John David Washington, Robert Pattinson, Elizabeth Debicki, Kenneth Branaugh, Dimple Kapadia, Martin Donovan, Aaron Taylor-Johnson, Himesh Patel, Clémence Poésy, Denzil Smith and Michael Caine. The film is now playing in theaters in select cities.
