Actor Chris Evans says Chris Hemsworth is "like a brother" to him.

The 33-year-old actor, who stars as Captain America in "The Avengers: Age of Ultron", has revealed that he and his Australian co-star, who plays Thor, have developed a strong bond over the years, in part because their careers have followed a similar trajectory.

Asked if Hemsworth is his best friend among the "Avengers" team, he told "Oh yeah, (Hemsworth) is like a brother at this point. We've had a very similar trajectory in, at least, being welcomed into this world.

"We both took these (Marvel hero) roles. We were both timid and nervous and didn't know how it was gonna play out. It's been nice to kind of share this with him."
