'A Good Day To Die Hard' Teaser Trailer: Sex, Smirks, And 'Splosions

I'll give it to Fox's marketing people: this first teaser trailer for the fifth John McClane outing, A Good Day to Die Hard, is zippy and fun. What happens in the movie? Who is McClane fighting, and why? Who's the guy with him? Why did that woman even bother wearing a bra if she wasn't going to wear a shirt under the leather? These questions are but trifles, because EXPLOSIONS! Lots and lots of explosions.

And, once again, Bruce Willis as McClane, with a wryly amused look in his eye and a smirk on his face. I missed that smirk. Get a dose below.

We know the answers to some of the questions I posed above: McClane and his son (that being the guy with him) are in Russia, where bad things are happening. Why? (Because its Russia? That might also answer the shirt/bra question. OK, I kid.) We don't know why. But we do know that John Moore directs and Jai Courtney (Spartacus) plays the younger McClane.

Yahoo has the teaser. A Good Day to Die Hard is an action valentine, as it opens on February 14, 2013.
