Bruce Willis' Daughters Settle 'Die Hard' Christmas Movie Debate

An age-old debate about Bruce Willis' signature film seems to have finally been resolved once and for all by his own flesh and blood -- and yes, Santa's coming to town!

We got Rumer and Scout Willis Tuesday in Beverly Hills, and while they seemed to be in a hurry -- they were nice enough to quickly answer a burning hot question that we just had to ask on behalf of the public and cinema lovers everywhere.

Namely ... is 'Die Hard' a Christmas movie??? That's what our photog was trying to ask, anyway, but Scout cut us off before we could even get the words out with a firm answer.

Check it out -- SW doesn't just say it once, but twice ... seemingly clarifying that this isn't just how she feels personally, but that this might be the position of the Willis family at large ... including Bruce himself. Ya gotta imagine they've talked about it as a unit.

This is a pretty big deal, frankly -- people have gone back and forth on whether 'DH' is actually a holiday-time classic. The plot takes place on Christmas Eve, but it came out during the summer of '88 ... and became a box office hit. Plus, it takes place in always-sunny L.A.

Also, Bruce recently revisited the Nakatomi Plaza building where the flick was shot -- overlooking the city from the top, just like he did all those years ago. So, yeah ... full circle.

Scout's position is different than Bruce's mother, though, we spoke with her back around Christmas and she said she didn't think "Die Hard" was a Christmas movie.
