The 31-year-old actor plays Lex Luthor in the highly anticipated movie, reported Ace Showbiz.
"Yes, it is like the most incredible character. It was written by this guy, Chris Terrio. This is like his first movie after 'Argo'. He's just this brilliant writer of characters," Eisenberg said.
"So, this movie is not this kind of cartoonish superhero movie. It is very serious and well acted, well written, well directed movie. It's really phenomenal!"
Eisenberg stars in "Batman v Superman: Dawn of Justice" along with Henry Cavill, Ben Affleck, Gal Gadot, and Amy Adams. Directed by Zack Snyder, the film is scheduled to hit US theatres on March 25, 2016.
