[The Week in Geek is a weekly Tuesday column that plunges headfirst into a deep pool of genre geekiness without ever coming up for air.]

Its a long-standing Marvel tradition that when two superheroes meet up, they've gotta fight. Usually it's due to some kind of misunderstanding, then the two make peace and go on their merry way as teammates against whatever looming threat has brought them to the same place at the same time. For Captain America and Thor, it's no different, and the two heroes found themselves pitted against each other in last weekend's Super Bowl.

This week, in a fight of trailer against trailer, 'Captain America: The First Avenger' versus 'Thor,' they're going to duke it out, big Jack Kirby splash page style. The two ads will compete in the following categories for the Best Marvel Trailer at the Superbowl: Origin Clarity, Villain Reveal, Sex Appeal, Money Shots, and Iconography. Who will win? Who will fall?
