Just in time for the holiday season, Marvel Studios is releasing its Marvel Cinematic Universe: Phase 2 Collection, complete with six Marvel theatrical releases (from "Iron Man 3" to "Ant-Man") and a bonus disc containing more than two-and-a-half hours of behind-the-scenes footage. CBR News has an exclusive clip from the box set's bonus footage, centered on the "Ant-Man" post-credits scene.

In the clip, Marvel Studios President Kevin Feige says that the decision to include a brief sequence from "Captain America: Civil War" at the end of "Ant-Man" came during his time watching dailies for the 2016 film. Feige highlights that the Russo Brothers, the directors of "Civil War," shot that particular sequence in a style similar to that of "Ant-Man," so he thought it was the right fit to include as the tag at the end of "Ant-Man."

"As fate would have it, the Russos had directed that scene in a similar fashion to the way Peyton [Reed] had done 'Ant-Man,'" Feige says in the clip. "I said 'Holy moly, this would be awesome. This could be the tag of the movie.'"

The Marvel Cinematic Universe: Phase 2 Collection will be on sale exclusively through Amazon starting Tuesday, Dec. 8.
