Jesse Eisenberg teased fans about his Lex Luthor role in “Batman v. Superman: Dawn of Justice.”

The 30-year-old actor explained to TotalFilm (via ComicBookMovie) he couldn’t dish an details about the production, but offered fans an interesting hint as to what they should expect from Luthor in “Batman vs. Superman.”

"There are some indications of how the character should behave based on the script, and then as actor makes it his or her own," Eisenberg said. "I got to know one of the writers really well, Chris Terrio, and we were able to discuss things at length and figure out who this person is to create a real psychology behind what is, perhaps, in a comic book, a less than totally modern psychology. I can only say I've been asked to play an interesting role: a complicated, challenging person."

Eisenberg also talked about the casting process for “Batman vs. Superman.” The actor explained his father always advised him against taking on role for a big payout if it’s not something he believed in. Eisenberg was adamant he didn’t attach himself to director Zack Snyder’s production because of the hype.

"They asked me if I wanted to play the part before they sent me the script. I'm not sure how it worked, but it's something I read with the understanding that I could do the role,” he told TotalFilm. “…You know, they don't just hand the scripts out. But I really liked it on its own terms. I would do it if it was for free and it was tiny."

The actor also knew being connected to the movie meant his life wouldn’t be the same once the film hits theaters.

"I've been in things that have been popular before," Eisenberg said. "To say, I can't do that which will appear in thousands of theaters on opening day, but I can do this which will appear in this amount of theaters...

“It's arbitrary. I realize how popular comic-book movies are, and now, working on one, I realize why they're popular - the story is really good, the dialogue is really good, the artistry behind every department is high, the acting is really good.”

“Batman v. Superman: Dawn of Justice” will be released to theaters on March 25, 2016.
