Jeremy Renner has been photographed walking into a hotel room, wearing a cap that has “Team Captain America” embroidered on the front.

That hat could be tipping fans off to Hawkeye’s allegiance in Captain America: Civil War. Or it might not be. Hats aren’t cannon, after all.

Renner joins an all-star Marvel cast for Captain America: Civil War. In the film, a feud between Captain America (Chris Evans) and Iron Man (Robert Downey Jr.) leaves the Avengers in turmoil. Joe and Anthony Russo direct.
