For a while now, Marvel has been including on their DVDs and Blu-rays short movies featuring support characters from their various franchises. Think of A Funny Thing Happened on the Way To Thor’s Hammer and Item 47, for example. The next one heading our way is Agent Carter, starring Hayley Atwell as Peggy Carter from Captain America: The First Avenger, which is set to feature Bradley Whitford, Shane Black and a few surprises.
Now, if you wanted to watch it, you could wait for Iron Man 3 to come out. Alternatively, you could watch this clip below.
