There are SPOILERS in the description for the preview, so consider yourself warned!
The footage begins with Falcon unveiling the MCU version of Redwing, which is a drone that he uses to scout for the threats. Captain America and Black Widow take on Crossbones, but Cap is taken aback when Crossbones mentions Bucky/The Winter Soldier. The end credits scene of Ant-Man is revisited when Cap asks Bucky if he remembers him. Tony Stark appears in the video and says that he wants to punch Cap in his “perfect teeth,’ Black Panther and Martin Freeman’s character are briefly seen before Hawkeye and Black Widow fight each other. The teaser ends with Ant-Man meeting Cap and Scarlet Witch for the first time…and he acts like a complete fanboy in front of the Avengers.
Captain America: Civil War will be out on May 6, 2016
