Captain America: The First Avenger
Visual effects shots of 1940s New York from "Captain America: The First Avenger" were reused in the short for budgetary reasons. D'Esposito noted the sequence where Carter comes "flying with the gun into the door" and the last fight, when Carter is "being attacked by the big guy", were both created with visual effects elements after they ran out of time to complete filming on them on set. In early 2013, Marvel approached visual effects company Perception to create the main-on-end title sequence for the short. Visual effects supervisor Sheena Duggal was told to retell the story of the short in 90 seconds, so she decided to use stylized versions of imagery from the period and the short itself. A mixture of 2D and 3D animation was used to achieve a final 2D look.
