In latest 'Batman v Superman: Dawn of Justice' movie news, a report revealed what secret weapon billionaire Bruce Wayne's alter ego will use in his epic encounter versus his fellow Justice League member, the 'Man of Steel', in the upcoming film.

According to the Batman News website, The Dark Knight will wear an armored Batsuit that will enhance his strength (in addition to firing missiles) when he battles Superman in the highly-anticipated blockbuster movie.

In addition, Batman's armored suit will also include Kryptonite, which is Superman's greatest weakness.

As most comic book fans know, Kryptonite is the mineral rock that originated after Superman's (aka Kal-El) home planet Krypton exploded immediately after the 'Man of Steel' (as a baby) escaped the now defunct world (via spaceship).

Affleck, who's set to play Batman in the upcoming film, revealed in an interview the differences between Batman and his 'Gone Girl' role, Nick Dunne.

"I was trying to juggle this thing because that character is supposed to be out of shape, hungover and and puffy and I had to train ahead of time for that movie [Batman] for about a year," said Affleck to ITV in an interview in reference to his aforementioned characters' distinct looks.

"I was trying to build underneath without looking like it. That wouldn't look right to have some guy who is in great shape because all Nick Dunne does is eat junk food and drink bourbon."

The new 'Batman vs Superman: Dawn of Justice' film stars Henry Cavill as Superman, Ben Affleck as Batman, Gal Gadot as Wonder Woman, Amy Adams (Lois Lane), Laurence Fishburne (Perry White), Jesse Eisenberg as Lex Luthor, Jeremy Irons as Alfred Pennyworth, Diane Lane (Martha Kent), Ray Fisher as Cyborg, Tao Okamoto, Callan Mulvey and Oscar Award winning actress Holly Hunter.

The 'Batman vs Superman: Dawn of Justice' film is expected to arrive in movie theaters on March 25, 2016.
