Jesse Eisenberg's Comic-Con experience apparently wasn't a joy.

Eisenberg, who plays Lex Luthor in the upcoming "Batman v. Superman, " was at the massive San Diego convention last week with co-stars Ben Affleck and Henry Cavil. In an interview Monday, he was decidedly negative about the experience.

"It is like being screamed at by thousands of people. I don't know what the experience is throughout history, probably some kind of genocide. I can't think of anything that's equivalent," he said.

Eisenberg spoke at the premiere of "End of the Tour," with Jason Segal, about the release of David Foster Wallace's novel "Infinite Jest." Segal plays Wallace, while Eisenberg plays journalist David Lipsky.

"Yes I have never been on the other side, on your side of journalism. I have normally been the victim so I worked with the guy who I play, I play a real person, David Lipsky," he said. "I interviewed him. He taught me how to interview and what his process is like and now I understand the pariahs that you guys are."
