The actress will play Claire alongside Jesse Bradford, who plays her boyfriend Benny. The story centers on the couple who stumble upon one of the discarded alien guns from the final battle scene in Marvel's The Avengers. The title refers to the actual gun itself, which leads the downtrodden couple to make some, "incredibly bad decisions." Maximiliano Hernández (Thor) and Titus Welliver are playing S.H.I.E.L.D. agents sent in to clean up the mess left behind by Benny and Claire. Here's what Marvel Studios co-president Louis D'Esposito had to say about the short, which he directed himself.

"The world is topsy-turvy now. There's been an alien invasion, and things are crazy. So when this gun ­literally fell into their lap, this is a sign: We're going to rob a few banks, we're going to buy a boat, we're going to the Caribbean, and all our problems will be solved."

Marvel One-Shot: Item 47 will be screened in its entirety at San Diego Comic-Con 2012. The studio is also developing new Marvel One-Shot scripts for Iron Man 3, Thor 2, and Captain America 2.
