Die Hard
Yes, it's totally a Christmas movie. Note the office Christmas party and the carols playing on the radio. And my favorite bit of the movie - "Now I have a machine gun. Ho-ho-ho." The second movie is also technically a Christmas movie as well, if you want more of Bruce Willis kicking terrorist butt.
There's a drug bust that goes down in a Christmas tree sale yard, the good guys leave a note for the bad guys on Murtaugh's Christmas tree, plus there's a group of police officers caroling at the station and Christmas decorations everywhere you look. That's enough to make this a Christmas movie in my book.
Watchable for both Halloween and Christmas, since it's set in Halloween Town during the weeks leading up to Christmas. Also, anyone who has been on Tumblr for any length of time probably cannot watch the song "What's This?" without hearing some different lyrics. Or maybe it's just the people I follow who keep reblogging those posts...
Beauty and the Beast: The Enchanted Christmas
I honestly like this sort-of sequel more than the original. From the very creepy pipe organ trying to ruin things for everyone to the lovely Christmas themes, it's a great holiday movie. And as a kid, I thought the storybook that Belle makes the Beast for Christmas was pretty much the best thing ever.
The Lion, the Witch and the Wardrobe
The scene where Father Christmas appears has always been my favorite part of both the book and the movie. It's no longer "always winter and never Christmas," and it's the first real sign that the White Witch's power has been broken. Plus, the soundtrack for that scene is incredible - it perfectly captures the joy of Christmas.
In my favorite Christmas TV episode, the Winchesters face down Evil Santa, plus we get flashbacks to young Sam and Dean, and a lovely piece of backstory for Dean's amulet. The bit with the eggnog at the end is great too, since Jared used real rum to spike Jensen's prop eggnog - a little bit of behind-the-scenes trivia for your added enjoyment.
Mulder and Scully investigate a haunted house on Christmas Eve, and get psychoanalyzed by some ghosts... This is honestly a very weird episode, even by X-Files standards, but although there are parts of it that make me cringe, these tend to be balanced out by the parts that are highly entertaining.
While not the only Christmas episode of Chuck, this one is my favorite. Yes, it's got some nice Die Hard references - the plot revolves around a hostage crisis on Christmas Eve, so those flow naturally. But the thing I really love about this episode is the number of strong character moments, including a couple of very important Chuck/Sarah developments.
I'm not a big fan of Doctor Who, or Moffat in general, but I like this episode quite a bit. Clara is seriously bad-ass, the snowmen are definitely creepy, and the Sherlock Holmes references are highly entertaining. If you're looking for another (mostly) stand-alone Christmas episode, Voyage of the Damned - which is set on an interstellar version of the Titanic - is also good.
Anyone else have other non-traditional Christmas movies or TV episodes that they like to rewatch during the holidays? If so, comment and share your favorites - I'm sure I overlooked some great ones.
