Matt Damon revealed how the script writer Chris Terrio played a role in Ben Affleck accepting to play the role of the Caped Crusader in “Batman v. Superman: Dawn of Justice.” The actor had previously talked about who would win if his fictional character Jason Bourne were to fight Batman.

In an interview with MTV, Damon was asked about the casting process of the DC movie. The actor agreed that he is excited to see the movie and pointed out that a “big decision” like being a cast member in the movie required deliberation, and Affleck did speak to him about it.

Damon said that Affleck knew what the stakes were at that time and revealed that when Terrio was selected to write the script of the movie, it “made the decision” for Affleck. Damon praised Terrio and said that he is a “fantastic writer.”

Another factor that apparently influenced Affleck’s decision was that he liked Zack Snyder, who is the director of “Batman v. Superman: Dawn of Justice.” Damon explained that Affleck felt that he had “all the pieces that are necessary” for a good movie and later accepted to be a cast member.

Damon said that he still hasn’t heard Affleck do his Batman voice from the movie and said that he is looking forward to hearing it in the movie. Affleck, however, may have revealed his Batman voice in this video. The video shows the actor saying “I’m Batman.”

In a recent interview with EOnline, Damon had said that his fictional character Jason Bourne would be able to beat Batman. The actor said that Affleck’s character will first have to take on Superman (Henry Cavill) in the forthcoming movie and then “maybe” he will get a chance to fight Bourne.

Damon is currently promoting his forthcoming movie “The Martian,” which is slated to be released on Oct. 2, 2015 in the U.S. He is also working on the fifth installment of the “Bourne” movie series that will be released in 2016.

“Batman v. Superman: Dawn of Justice” is slated to be released on March 25, 2016 in the U.S. Some of the cast members of the movie include Gal Gadot (Wonder Woman), Jason Momoa (Aquaman) and Jesse Eisenberg (Lex Luthor).
