The first footage from Captain America: The First Avenger has hit the net thanks to Paramount's Super Bowl Spot.  If you were debating about the movie...this spot is going to shut you up.  While I was a bit nervous how they'd show the transformation from a skinny Steve Rogers to Captain America, the commercial just calmed my nerves.  I love how thin Chris Evans looks at the beginning in boot camp and then how buff he is after the serum.  Well done Marvel.  Well done.  Watch the spot after the jump.

Captain America: The First Avenger hits July 22, 2011 and stars Evans, Hugo Weaving, Tommy Lee Jones, Dominic Cooper, Hayley Atwell, Sebastian Stan, and Stanley Tucci.
