Watch Comedy Central's "Bruce Willis Roast"...he specifically said, he agreed to be roasted to set the record straight "Die Hard IS NOT A CHRISTMAS MOVIE!". As much as we would like it to be. Sorry folks!
It is a Christmas movie because Christmas is important to the plot. Gruber plans for the heist to happen during the company's Christmas party so the building would be mostly empty, and they could get to Takagi. Maclean is in LA to visit his wife because it's Christmas.
@bethorein...SIMPLY relaying information I viewed..."I don't have the time, nor the crayons to explain this to you. Confrontation isn't your thing but you obviously like feeling superior! Do you always satisfy your a superiority complex behind your computer screen. Remember when I asked for YOUR opinion...yeah, me neither.
