Matt Damon and Ben Affleck will never stop acting together even if they "oversaturate the marketplace"

Matt has revealed how he started crying after watching Peter Jackson's Beatles documentary Get Back, which concluded with a title card noting how they had never worked together again.

Speaking to GQ magazine, he recalled telling Ben: "Who cares if we oversaturate the marketplace with movies we're both in?

"We're crazy if we don't take advantage of the fact that we are both still here and able to do this."

In The Rip, the pair fall into type, with Ben in a more flamboyant role, and Matt playing the more pensive character.

Matt quipped: "Well someone's gotta put the movie on their back.

"I don't know-maybe he's just a more versatile actor than I am. But I don't think that's intentional.

"I think it's just worked out that way. But we got more movies to make together, so maybe we can switch it up a little more."

His friend laughed at the idea he has "all the fun", but insisted the dynamic has been there for almost 30 years.

He explained: "I bet Matt wouldn't trade places with me. I think that [dynamic] started in some ways with the Good Will Hunting template - and also frankly because Matt has probably always been considered a more bankable or reliable leading man, maybe?"

Ben insisted his friend is "so understated" and real, which can be a much "more difficult" skill.

He said: "Every time I act with Matt is a humbling experience because I learn to appreciate further just how good an actor he is.

"He is so understated, so real and so honest - it's the opposite of a 'showy' performance, and I think what he does is more difficult.

"When you know someone as long as I've known Matt, you develop a pretty good sense of what is real and what isn't and it's almost impossible to catch Matt acting.

"He is really a master of realism and it's something I deeply admire about him. One of many things."
