A while back, I attended the press junket for “21 Jump Street,” which is one of the funniest movies I’ve seen since “Bridesmaids.”

I know, it seems insane to write that — after all, it’s a movie based on a TV show from the ’80s, and those are never good. But that’s the case, folks. I was laughing from the first scene to the very last, and then again throughout the credits. And what’s more, the jokes were actually (*gasp*) intentional.

So if you’re looking for a good laugh this weekend, you can’t go wrong with “21 Jump Street” (or “Casa de mi Padre,” for that matter).

Here’s an excerpt from my interview with “21 Jump Street” actor Rob Riggle in which I ask him about all of the improv I keep hearing about, as well as a particular scene (don’t worry, I keep it spoiler-free) that made me and everyone else in the theater recoil in horror. Oh, and I also ask him a few questions about all those “Call of Duty” ads he keeps appearing in, given that he’s an active Marine on top of being an actor.

IFC: There’s great chemistry between everyone in the film — especially when you, Jonah, and Channing are in scenes together. It seems like it was as much fun to perform as it is to watch. Was there as much improv as it seems?

RIGGLE: There was a lot of improv, yeah. The script was really tight, and that was great, because we would do lots of takes from the script with notes and without notes and get the scene just right. But then Chris [Miller] and Phil [Lord] and Jonah were really good about saying, “Okay, let’s play a little bit. Let’s see what you’ve got.” So we’d improvise and play, and we all trusted each other enough that we felt comfortable bringing ideas and throwing stuff out there to try. I think in the movie you end up seeing a lot of scenes that were improvised, and you can see how it has that loose, natural feel about it. That’s why we ended up cracking each other up a lot, because we kept catching each other off guard.
