'Zombieland 2' filmmakers on the series' best cameos and bringing back you-know-who for 'Double Tap'

Spoiler warning: The following story reveals surprise elements of "Zombieland 2: Double Tap."

Arguably the funniest moment of 2009's undead comedy "Zombieland" comes when the intrepid gang of survivors - Columbus (Jesse Eisenberg), Wichita (Emma Stone), Tallahassee (Woody Harrelson) and Little Rock (Abigail Breslin) - discover that comedy legend Bill Murray has found a foolproof way to survive the zombie apocalypse: disguising himself as one of the walking dead.

"He was the highlight of the first movie," said Paul Wernick, who, with Rhett Reese, co-wrote the script of both the original and its sequel.

But Murray's attempt at pranking Columbus backfires and he is accidentally killed, limiting his cameo potential for the sequel.

"There is no world of 'Zombieland' without Bill Murray," Wernick said.
