After the zombie apocalypse has wiped out the majority of civilized society, pickings are slim for human companionship, especially if you want to hang out with someone who's not interested in turning you into a meal. And rather than navigate the perilous landscape solo, you take what you can get.

Zombieland's comic odd couple couldn't be more opposite in their approach to survival. While Tallahassee (Woody Harrelson) has turned zombie killing into a sport, always in search of a new and inventive way to pick off the undead, Columbus (Jesse Eisenberg) has developed a lengthy set of rules for survival in the post-apocalypse. Meanwhile, Wichita (Emma Stone) is primarily focused on protecting her sister Little Rock (Abigail Breslin) and keeping them both alive as long as possible.

During our April visit to the set of Zombieland in Rutledge, Georgia, Bloody-Disgusting had the opportunity to speak with Harrelson, Stone and Eisenberg between takes. Despite a first time feature director in Ruben Fleischer, the production was a week away from wrap, on schedule, on budget and still maintaining a surprisingly fun-spirited atmosphere.

"It's just been really fun," Emma Stone tells press. "I got to learn how to shoot a pump shotgun and load it. It's been exciting. The script is just completely different from anything I've ever read. This is just a real reaction in a comedy sense of what these people would do if zombies took over the world. I just love this girl just because it's different from anything I've gotten to do. It's been a bigger challenge than I thought it would be, in a good way."

As the comic odd couple of the zombie apocalypse, Harrelson and Eisenberg's characters are slow to adjust to one another's wildly different takes on survival, but eventually they get along and even rub off on one another a bit.

"I'm very cautious about surviving," says Eisenberg. "[Tallahassee] gets a thrill out of being aggressive and killing. If there's a zombie coming, I flee and he just wholeheartedly goes in and tries to kill, so it's a funny dynamic. I have a list of 47 rules on how to survive Zombieland, and towards the end of the movie, I start either crossing them off or modifying them because they just make my life a nightmare... [Tallahassee] has zero rules to survive Zombieland, so it starts to rub off a little bit.

"That's completely true," says Harrelson. "There's one, where he always limbers up before he does things, because it's cardio. There are several things that are fundamental to survival, according to his guide book, and towards the end, I do a little bit of limbering up."

Despite the varied roles Harrelson has gotten to play over the years, action hero is a part he has rarely been offered. He admits he's had a great time filling the role. "I really love my character, Tallahassee. I loved the script - just generally, such a beautiful, well-written script, so funny – and Tallahassee's a lot of fun. He's just this shit-kickin' kind of guy who's really got this broken side to him."

During the reel of footage Fleischer showed press, one of the standout moments involved Stone upping her ample sex appeal by toting a machine gun, mowing down zombies with reckless abandon. Stone laughs when we bring up the scene, admitting she's still unsure of whether or not she pulls it off. "I haven't really seen any footage of myself being heroic," Stone says nervously. "I'm a little terrified to see that, a little horrified."

Although Stone went through training for the gun scenes in Zombieland, she says she's still not ready for live ammo. "I wouldn't trust myself with a real gun all the time. I'm the clumsiest person in the world, and bad things would probably happen if I owned a gun."

Likewise, guns are a new experience for Eisenberg. "Guns are heavier than they look," Eisenberg says with a level of exasperation. [I] just wanted to tell anyone who watches the movie, guns are heavier than they look when you carry them in your hands."

The cast of Zombieland was thrown into the production head first, shooting the film's climactic amusement park sequence before any of the dialogue or bonding moments.

"Initially, it was kinda odd," says Harrelson. "Really odd. They had to do it logistically, but once we were into it, it was almost better to do it that way. I know personally, I had some ideas, some things I was going to try character-wise, a stuttering affectation... and I'm just glad I didn't. It's better that we just started off doing the action stuff."

"All the stuff at the end of the movie is action-oriented, so it's more of a gradual way of getting into it," says Eisenberg.

Spirits were high during our visit, roughly a week away from production wrap. Part of the day's enthusiasm might have centered around the scene shooting that night, in which the cast decides to smash up an Indian trading post for fun. "There's gonna be some tussles later on over who gets to do what," says Harrelson with his trademark cheshire cat grin.

Before the cast got back to set, we asked them what zombie kill was their personal favorite.

"We're in a grocery store and there's a zombie chasing me," says Eisenberg. "[Woody] has a baseball bat, and I slide under his bat on my knees, so just as he's swinging, it hits the zombie and not me."

Harrelson laughs about the moment for a second, before agreeing that the scene was also his favorite kill. "I kinda like the thing with the bat," says Harrelson. "At the risk of being boring and redundant. Of course, that never stopped me before."

ZOMBIELAND arrives in theaters October 9th.
