2017 - 45: Lights, Camera, Christmas! Inside Holiday Movie Classics

The special will include insider details on classic holiday films including a casting decision, Jim Carrey's torture-surviving technique training during "How the Grinch Stole Christmas"; and a visit to a Vancouver psychiatric hospital, the stand-in for Gimbal's toy department in "Elf." The hour will consider the question of whether favorites such as "Trading Places" and "Die Hard" qualify as Christmas movies; and talk to a spokesperson from Rotten Tomatoes to discuss what it takes to qualify as a Christmas classic. The history of small-screen favorites such as "A Charlie Brown Christmas" and "Rudolph the Red-Nosed Reindeer" will be featured, as well as interviews with the voice-over artists behind these favorite animated characters, and the owner of the fully restored Santa and Rudolph puppets.
