Iron Man 2 – After-credits scene description

“We see a black car drive through the desert of New Mexico. They make sure to tell us it’s New Mexico by showing a closeup of the license plate which reads 8RE 2Z1 New Mexico. The car door opens and Agent Coulson walks up to a giant crater. There are trucks driving around a big hole in the crater. Agent Coulson turns around, gets on the phone and says, “Thor. We’ve found him.” (He could also be saying, “Sir, we’ve found it.” I couldn’t exactly tell, the audio wasn’t that great).

The camera then cuts to a shot of Thor’s hammer stuck in the ground in the middle of the crater.”
