Scarlett Johansson's Black Widow Takes on Hawkeye in Japanese 'Civil War' Trailer [VIDEO]

Alliances will definitely be tested in Captain America: Civil War, as friends like Black Widow and Hawkeye find themselves on opposite teams for the first time. But will Scarlett Johansson's Natasha Romanoff be able to beat Jeremy Renner's Clint Barton in the fight between Team Iron Man and Team Captain America?

A new international trailer offers a quick glimpse at what could happen if trained fighters and close friends end up having to fight one another. Although the Japanese teaser features mostly the same footage in the second Civil War trailer, it has an unexpected new scene showing Black Widow going up against Hawkeye.

The scene shows Clint pinning Nat down with his bow, making the former Russian assassin ask, "We're still friends, right?" The sharpshooter simply responds that it would depend on "how hard you hit me."

The friendship between Natasha and Clint isn't the only relationship that appears to be on the rocks in the Civil War trailers. The second teaser also showed Scarlet Witch (Elizabeth Olsen) using her powers on Vision (Paul Bettany), who can be seen struggling on his knees.

Perhaps the most compelling aspect of Civil War is the conflict between Steve Rogers (Chris Evans) and Tony Stark (Robert Downey Jr.), as Cap declares that he wishes he could look away when "a plan is going sour." Tony promptly replies, "Sometimes I wish I could punch you in your perfect teeth."

With only a little over a month left before the release of Civil War, the film is already getting positive reviews from its own stars. Sebastian Stan, who will reprise his role as Bucky Barnes in the third Captain America movie, has already admitted that the film left him at a loss of words.

"I walked out of it speechless, and I worked on the movie and I was there!" Stan told Collider. "I walked out of there and I had back pain from leaning."

Captain America: Civil War will hit theaters on May 6.
