Director Fury wants me in New Mexico.
The extra scene in the credits of this film is Agent Coulson arriving in New Mexico to find Thor’s hammer. The Mystery Mesa aka Agua Dulce Movie Ranch Inc. was used for this sequence in both Iron Man 2 and Thor.
Shortly after the final scene from Iron Man 2, where Agent Coulson finds the crater of the crashed hammer of the god of thunder, SHIELD agents set up a perimeter around the mysterious object to study it.
