Bill Murray's cameo was a welcome and hilarious surprise in Zombieland. But it may be one of the last, great cinematic reveals. As the recent Mel Gibson/Bill Clinton cameo news in The Hangover Part II has shown, studios are out to ruin their own surprises. And that is certainly the case with Sony Pictures' Zombieland 2.

Bloody Disgusting has learned that director Ruben Fleischer intends to one-up the Bill Murray cameo magic he captured with his first film, and that Harrison Ford and Anthony Hopkins are the two leading choices to appear as themselves in Zombieland 2. Neither actor has signed on at this point. But it surely won't be a surprise by the time this sequel hits theater screens.

The script for Zombieland 2 will also introduce a new lead villain with comedic roots, and a handsome rival who will be going head-to-head with Tallahassee (Woody Harrelson). At this time, Harrelson and Jesse Eisenberg are the only two actors officially signed to appear in the sequel.
