Chris Evans and Minka Kelly fuel rekindled romance rumors...

When Chris Evans and Robert Downey Jr. team up, it’s going to be a good movie.

Except this time, their characters Iron Man and Captain America find themselves at odds.

In the brand new trailer released by Marvel Entertainment, Captain America is back, but this time his feud with Iron Man is driving the Avengers apart.

But don’t worry, Evans and Downey Jr. are actually friends in real life. “I feel partially responsible, you had a little bit of doubt coming into the Marvel Universe,” Robert said of Chris while they were appearing on Jimmy Kimmel Live.

“It was a big commitment, you know, these contracts are six… nine movies long.” Chris said. “He’s not a guy that likes to be held down, ladies.” Robert joked.

The guys revealed they filmed the movie in July in Atlanta, which they described as ‘Hotlanta.’ “Once the helmet closes, I’m not there,” Downey Jr. joked about staying away from the heat during filming.

“I maybe would’ve chosen not Atlanta in July…” Chris chimed in.

Robert added that it has been a pleasure to work on the many films in the franchise that he’s been a part of. “It’s the best thing that ever happened to me. It’s just been a great job, and we’ve all made good friends and stuff,” he said.

Captain America: Civil War will hit theaters on May 6, 2016.
