> Do mildly Christmas-themed movies such as Die Hard (it's not integral to the plot)

The plot of the movie would have to be changed substantially if it didn't take place at Christmas, so I think it is integral to the plot.

The plot would have to change, but very little of importance. Instead of an evening Christmas party, it could have been an evening party celebrating the opening of the building. And don't write ho ho ho on the terrorist you put in the elevator. Done.

It stains my credulity to think he would fly cross-country just for an office opening party
