As horror movie remakes go, "Black Christmas" may be obscure enough that today’s audience doesn’t remember it. But just to be sure, the filmmakers are crafting a new ending to shock audiences. Even star Mary Elizabeth Winstead doesn’t know what the final release version will be.

“I really don’t know what to expect because they’ve been editing and reshooting and editing and changing things around,” she said. “So I’m going to be just as surprised as everyone else I think when the movie actually comes out. I think they reshot the ending and I’ve been kind of out of the loop because I’ve been working on other things, so I think the ending might actually be different than what I knew of.”

You’d think an actor would know if she went back to reshoot more scenes, but Winstead kept her involvement in the reshoots vague. “Well, I can’t say. They don’t want anyone to know who lives and who dies so I kind of stay out of that.”

"Black Christmas" is schedule for Christmas Day 2006. “Counter-programming I think is what they’re saying.”
