According to Bruce Willis, Die Hard 4 is still in the works. A recent interview with Maxim Magazine has the actor hinting around at what's going on with the production...

"It's Die Hard 4.0. They're working on the script right now. Doug Richardson, who wrote Hostage is typing away furiously. It's a really interesting idea. And it's the first one that Fox has liked, so we'll see.

Maxim continues: Yippee-ki-yay! What's the plot?

I can't tell you a thing about it.

Nothing?

I can't tell you a thing about it.

Dude!

John McClane is retired. I can tell you that.
