Eisenberg offers this version of Lex Luthor is a great character as well as stating Lex isn't a silly villain and is different than the Gene Hackman Luthor.
Here's the blurb:
It was a wonderful opportunity.
It’s a really great character that’s written by this guy, Chris Terrio, he’s a phenomenal writer. He comes from a place of character. He loves my character in the same way I love my character. He put a lot of work into it. It’s a great character, there’s an emotional core to the character. It’s not silly, villainous character. It was a great part.
Eisenberg continues with mention his Lex Luthor is entirely different than the Gene Hackman version.
No. There is no way to do anything. I mean its an entirely different thing, but also the tone of that movie is so different... that movie wouldn't be made like that now... The way we expect movies now is to have some kind of... I mean it's for the best probably because there is some kind of more psychological accuracy... that the person is coming from a place that's probably diagnosable.
This is a real depiction of a person who thinks these things.
