Two weeks after announcing that a new "one-shot" short film starring Agent Peggy Carter from Captain America: The First Avenger would be accompanying the new Iron Man 3 Blu-ray set, Marvel has released the first clip, which features actress Hayley Atwell as the title character making short work of some impolite thugs.
