Christopher Nolan’s “The Odyssey” was an epic undertaking for all involved. The cast and crew embarked on a globe-trotting mission to bring the story of Odysseus’ homecoming to life in the most realistic way possible. Here’s a look at “The Odyssey,” in theaters Friday, by the numbers.172: Runtime, in minutes, for “The Odyssey”It’s shorter than “Oppenheimer” (180 minutes), which was at least partially because IMAX film projectors can’t handle more than three hours. “It’s an epic film, as the subject matter demands,” Nolan told The Associated Press. “But it is shorter.” In case you don’t want to do the math, that’s 2 hours, 52 minutes. 91: Days of shootingThe shoot happened across six months though it was scheduled for 100 days. The efficient production finished nine days early.“I found that after 100 days, it’s very diminishing returns. It’s very tough to keep getting new material because everyone’s so exhausted,” Nolan said. “We finished a little early because a lot of things broke our way in terms of weather or getting the conditions we needed or wanted to make particular shots. And at the end of that 91 days, I certainly couldn’t have done another 9 days, so I think the shoot took the length of time that it needed to take.”
