Although it's his older brother who stars in this holiday classic, Kieran Culkin appears in Home Alone as one of the many children in the house who are fighting over pizza and Pepsi.

They say when destiny has a sense of humor you get serendipity. The fate of two people hoping to connect was all in Eugene Levy's hands when he played a very important salesman in this Christmas love story.

Christina Hendrix joined the holiday debauchery that was Bad Santa 2, playing the head of a charity organization. It was as raunchy as you would expect.

Jessica Biel was at the height of her 7th Heaven fame when she played Jonathan Taylor Thomas's love interest in I'll Be Home for Christmas. It is peak '90s and as amazing as it sounds.

The singer/actress took her pipes off Broadway to grace us as Danny Devito's wife, Tia Hall, in Deck the Halls. We say, the more Chenoweth, the better. (More on Kristin Davis later.)

Dan Aykroyd plays an uptight neighbor competing against Tim Allen and Jamie Lee Curtis throughout the holiday season in Christmas With the Kranks. Classic.

Why wouldn't Neil Patrick Harris perform a song and dance number while wearing a top hat and holding a giant candy cane in A Very Harold & Kumar Christmas?

Before she roamed the Upper East Side on Gossip Girl, Taylor Momsen was the adorable Cindy Lou Who in How the Grinch Stole Christmas.

He may have left Downton Abbey, but Dan Stevens wasn't done with period dramas just yet. His role as Charles Dickens in The Man Who Invented Christmas is memorable, mostly due to his drastic hair change for the role.

Okay, so he's in a coma for most of the movie, but Peter Gallagher was dreamy enough to cause Sandra Bullock to lie about an engagement, so we have to give him some credit.
