"I can't see it working the other way, because my character wants to be friends with his character more than his character wants to be friends with me. I kind of feel like that's how it is in real life," Franco said. "I'm interested in what he's interested in and he just doesn't reciprocate."
"I've tried to," Rogen responded. "This is like a conversation I've had with my girlfriend."
With "Pineapple," writers Rogen and Goldberg attempted to fuse their favorite disparate genres of the stoner flick and big budget action movies, resulting in the mutant "stoner action-comedy" tag. Rogen, in fact, loves action movies so much that he even dragged co-star Franco to the opening night of "300."
"You've never seen a guy more excited for anything in your life," Rogen remembered of himself from the experience.
For Franco, the event was rather different. "I was the one guy who fell asleep," he said.
"So, those were the types of movies I always wanted to make, and I knew that comedy was definitely where we've made the name doing," Rogen said. "It's a lot of fun to do, but we thought if we can kind of start injecting some of these other kinds of genres that we're big fans of into what we've been doing, maybe that can make an interesting combination."
The film was Rogen's first foray into the action genre. Franco is known to action fans as Harry Osborn, son and heir of the Green Goblin from the Spider-Man films.
However, Franco was not immune from the perils of the stoner-action comedy. During filming of the memorable forest chase scene, fueled more by scripted THC-induced paranoia than actual danger, Franco ran into a tree, splitting his head open and resulting in stitches.
"I really ran into the tree, and if you laugh at that scene, you're laughing at me cutting my head open," he said.
In order to make the movie, some standards of the loveable slacker genre had to be subverted, as well.
"Cheech and Chong paved the way and we owe a lot to them, but if you watch those movies, there's not too much plot or story," Franco said.
"And if you're not really stoned, you probably will not enjoy those movies all that much," Rogen added. "So, there was a lot of discussion about how do you make a movie that's about weed, but you don't really need to be stoned out of your brain to enjoy it. The answer was to try and add more of an emotional story to it, and things you'd expect more out of the comedies we've been doing, but just kind of add the weed as one of the many elements that the comedy comes from."
However, the two want audiences to thoroughly enjoy the "Pineapple Express" experience.
"I want them to feel happy, I want them to feel like they saw something they've never seen before, and I like it when people truly wonder how we got this movie made, which is something I wonder every time we watch it, you know, " Rogen said.
"I think it's exciting and something that you feel you shouldn't be watching, in a weird way. It feels a little against the rules of kind of these big studio movies to me, so, that I find cool."
The duo admitted that, if approached for a sequel to "Pineapple," they will be taking a far different tone.
"We keep thinking, why is weed the only drug that gets its own comedies? Why are there no crack action-comedies?" asked Rogen. "'Judgment P,' that's what we're calling it. 'P2: Judgment P.'"
