Yesterday we gave you some great shots of Thor and Loki in full costume with Captain America on his motorcycle and the rest of the cast assembled in street clothes, today we have some more exciting shots of the Avengers in action!

These new shots include great looks at Captain America, Black Widow and Hawkeye and also features Loki and Thor with their hands inside some kind of device. If our speculation is correct, this may be a device meant to send them back to their Asgardian realm.

Thanks again to CeleBuzz and Just Jarod (via CBM) for the pictures!
