Patricia and David Keighley, Imax execs and two of Christopher Nolan’s longest collaborators, seen with reels of the 2023 film “Oppenheimer.” At the premiere of “The Odyssey” at the BFI Imax, Nolan dedicated the film to his memory. That means that in the past, dialogue-heavy sequences shot with Imax cameras were unable to also capture usable live sound from the actors. Christopher Nolan and DP Hoyte van Hoytema use the Keighley Camera to film Matt Damon and Zendaya on the set of “The Odyssey.” There was about two years between that release and when shooting on ‘The Odyssey’ started, and that’s about how long we spent at Imax designing the Keighley camera,” Keighley said.
