Apparently, Jesse Eisenberg’s Comic-Con experience wasn’t a fun time. 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 Cavill. In an interview Monday, he was decidedly negative about the experience. The actor said, “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.” Eisenberg also spoke at the premiere of his other movie, “The End of the Tour,” with Jason Segel, which centers on the release of David Foster Wallace’s novel “Infinite Jest.” Segal plays Wallace, while Eisenberg plays journalist David Lipsky.
