No, Jim doesn’t hate Christmas. He did hate all that prosthetic make-up, though. So much so that in the end, he had counseling from some Navy SEALs. They taught him torture resistance techniques to keep his mind off the make-up and on the film, and he managed to do a stellar job of making us laugh despite it all. Kudos, Jim. He did get some breaks where possible – for example, the yellow contact lenses were ditched frequently, and Jim’s eyes coloured in post-filming.
