Even though The Odyssey is the first movie to be shot exclusively on IMAX cameras, the epic still had to adhere to the company's runtime limitations, despite how much director Christopher Nolan tried to work around the constraints.
"It's still three hours on the film prints, said Nolan in an interview with Letterboxd. The Odyssey's runtime is 2 hours and 52 minutes, but after the director had previously pushed IMAX to its limits by making Oppehnimer exactly three hours long, he planned to make his ancient Greek epic run even longer. However, Nolan's IMAX mentor of 20 years, David Keighley, set him straight.
