Garrett Hedlund was inspired by co-star Hugh Jackman while training with him for their action scenes. He said, "Hugh's amazing. He sets a standard for young males all over the place. He puts 110 percent into everything he does, including fitness. Hugh and I trained with this wonderful trainer named David Kingsbury. We got some gym sessions in together. It's a lot to keep up with, but it's wonderful to see someone who works out as hard as he does, it's inspiring."
In February 2016, Rooney Mara gave an interview to The (London) Telegraph in which she said that she (a white performer) regrets playing Tiger Lily (a Native American character) in Pan: "I really hate, hate, hate that I am on that side of the whitewashing conversation. I really do. I don't ever want to be on that side of it again. I can understand why people were upset and frustrated....Do I think all of the four main people in the film should have been white with blonde hair and blue eyes? No. I think there should have been some diversity somewhere."
Dario Marianelli, a collaborator on Joe Wright's films and the Academy Award-winning composer of Atonement (2007) and V for Vendetta (2005), was Wright's original choice to compose the music for Pan (2015). However, a Warner Bros. executive may have found Marianelli's completed music unsatisfactory and inadequate and was dropped out of the production. Wright eventually replaced Marianelli with John Powell, who is best known for his universally acclaimed and Academy Award-nominated score for How to Train Your Dragon (2010).
Pan (2015) was originally scheduled for a July 24, 2015 release, but post-production issues and Joe Wright's change of composers maybe are the reasons the film's release was changed to October 9, 2015.
