Captain America: Civil War shows Downey and Cheadle reprising their roles yet again - Downey as Iron Man and Cheadle as War Machine. After doing three films together, their bond seems to be growing stronger and better than ever.

Signs of the apparent bromance seem to surface when ET reporter Nichelle Turner noticed and asked about made-up bruises on Downey's face. The Oscars nominee then joked saying, "I spoke about something having to do with 'Civil War' that I wasn't supposed to and Don touched me up."

Cheadle responded saying, "Hey man, I do what Marvel tells me to."

Downey noted that he got all the bruises but Cheadle comes out clean without a scratch on his body.

Captain America: Civil War revolves mainly around the rift between Captain America (to be played by Chris Evans) and Iron Man. The rift comes from the two characters' different opinions on an accountability scheme that a governing institution would like the heroes to utilize.

Although the movie is much about disturbance and dilemma among the Avengers, Downey Jr. says that the only partnership Iron Man needs to maintain was that of Cheadle's role as War Machine. He said that as long as Iron Man has War Machine, he does not really care about the rest of the heroes.

Captain America: Civil War is set to hit the theaters in IMAX 3D and in 3D on May 6.
