The actor appeared on “The Tonight Show” where he told Jimmy Fallon that “Deadpool” is the reason for the delay.

Eisenberg explains that “Zombieland: Double Tap” screenwriters Paul Wernick and Rhett Reese’s plans for the zom-com got pushed to the side when they got involved in creating “Deadpool” and “Deadpool 2”.

“We were trying to do the movie right after the first one ’cause the first one was so popular and then we just waited for the best script,” Eisenberg told Fallon. “In the meantime, the two writers, Rhett Reese and Paul Wernick, did ‘Deadpool’ and then we were waiting for them to finish that so they can write this. And we were all waiting, me, Woody Harrelson, Emma Stone, Abigail Breslin, we’re all waiting for the best script and it finally came in.”

Eisenberg talked about Zoey Deutch’s performance in the sequel, saying, “it was impossible to keep a straight face” while filming. “Everything she did was so unbelievably funny,” he noted.

“Zombieland” hit theatres in 2009. The apocalyptic comedy about a zombie virus outbreak followed four survivors, Tallahassee (Harrelson), Columbus (Eisenberg), Wichita (Stone), and Little Rock (Abigail Breslin). The four stars return to their roles in “Zombieland: Double Tap” where the survivors fight new zombies in the American Heartland.
