Just a few weeks ago, Marvel debuted the first trailer for Captain America: Civil War, which proved to be a huge hit with fans. The trailer was watched a whopping 61 million times in the first 24 hours of release, and it's clear that Captain America: Civil War could be one of the biggest movies of 2016. It isn't known yet when the next trailer will debut, but until then, one of the superhero ensemble's stars, Jeremy Renner, shared a new behind-the-scenes photo on his Twitter account, featuring the actor in character as Hawkeye, alongside Elizabeth Olsen's Scarlet Witch.

This image gives us our best look at Hawkeye and Scarlet Witch's new costumes in Captain America: Civil War, since we didn't see too much of each character in the trailer. Of course, we don't know where in the movie this scene is from, but it shows Hawkeye drawing back an invisible arrow while Scarlet Witch looks on. Since they don't seem to be in any immediate danger, it's possible that Hawkeye may be teaching Scarlet Witch the art of archery, even though she has her own supernatural ways of defending herself.

In this summer's Avengers: Age of Ultron, it was Hawkeye who eventually convinced Scarlet Witch to fight alongside Earth's Mightiest Heroes, so perhaps we may see more of their relationship develop in Captain America: Civil War. That's all speculative at this point, but we do know that both of their costumes have underwent some significant changes. Hawkeye's attire is getting closer and closer to the iconic purple outfit from the comics, while Scarlet Witch was given an upgrade as well. We only saw her in full costume at the very end of Avengers: Age of Ultron, but this image shows that her new outfit is a brighter shade of crimson red, with longer coat tails.

Back in August, new promo art confirmed that Team Cap includes Hawkeye (Jeremy Renner), The Winter Soldier (Sebastian Stan), The Falcon (Anthony Mackie), Sharon Carter/Agent 13 (Emily VanCamp) and Ant-Man (Paul Rudd). Iron Man's team includes Black Panther (Chadwick Boseman), War Machine (Don Cheadle), Black Widow (Scarlett Johansson) and Vision (Paul Bettany). Scarlet Witch was the only main character who wasn't featured in that artwork, but new photos released last week from the splash page fight shows that Scarlet Witch is in fact fighting with Hawkeye on Team Cap.

In addition to this photo, the French website Skriptfr has debuted new pieces of promo artwork for Captain America: Civil War, which hits theaters May 6, 2016. The artwork gives us a new look at both Cap and Iron Man engaging in battle, while another showcases just a few of each side's team members in a unique way. While we wait for more on Captain America: Civil War, take a look at these new images below.
