The Film Had a Massive Budget

Surprisingly, Christmas Vacation had a giant budget, especially for a comedy film. The budget was $27 million, although there weren't nearly as many special effects as a movie like Ghostbusters, which was made similarly for around $30 million.

The size of the budget proved to not be an issue, as it made the budget (and then some) back after the film's final domestic gross was $71,319,526. This was extremely impressive for a Christmas film.

The Griswold's Reuinted for an Old Navy Commercial

During the holiday season of 2012, Old Navy released a series of commercials to promote their holiday sweaters that featured various members from the original Griswold family. One of the commercials included the original Rusty, Euro Rusty, Audrey, Juliet Lewis, Chevy Chase, and Beverly D'Angelo.

However, actor Johnny Galecki was noticeably missing along with Euro Audrey actress, Dana, Hill who had passed away in 1996. Another one of the commercials that aired had only Beverly D'Angelo and Chevy Chase along with Johnny Mathis.
