The film is based on John Grisham's book "Skipping Christmas." (The original title is seen in the newspaper article after the tanning salon incident.) The title was changed to avoid confusion with Surviving Christmas (2004). Both movies were holiday comedies released in the same year and both were poorly received by critics.
The swimsuits the models are wearing in the advertisement for the cruise the Kranks are taking are the same ones Luther and Nora wear when they go tanning in the mall.
When Luther is stuck hanging from his roof, you can see one of the fireman get hit in the face with the ladder.
During filming, it was reported that the cast and crew had ingested over 10 pounds of fake snow.
