No matter what you thought about Adam Sandler's last few zany comedies, there are more than a few reasons to be excited about his next release, "That's My Boy."

First, it's Sandler's first-ever R-rated comedy. Second, it features a cast of former and current "SNL" players like Andy Samberg and Will Forte, as well as James Caan and Vanilla Ice. And third, the outrageous plot revolves around a deadbeat father (Sandler) who attempts to reconnect with his long-lost son (Samberg) on the week of his wedding.

MTV News recently caught up with funnyman Forte to find out all about the on-set antics, Sandler's genius abilities in the art of swearing, how awesome Vanilla Ice is in the film and if we'll ever see a "MacGruber" sequel.

MTV News: In looking at the cast and concept of this film, it seems as though you probably had a lot of fun on set.

Will Forte: It was a ton of fun. I've always watched Sandler movies and thought, "Oh my God, that looks like it would be so much fun." They're always in Hawaii or some glamorous setting, and it really is as much fun as you would think it would be. It was like going to summer camp for this. Everyone was so cool. He's such a loyal and good person. He always works with the same people on the crew, so it's a real family-like atmosphere.

MTV: How does your character fit into the mix?

Forte: I play this guy named Bill, and he is Andy's best man. I don't really know Andy that well, so you find out later when Adam comes to find Andy on his wedding weekend, I give up my best-man duties to Adam. It's definitely not a straight man; he's kind of a weirdo. It's a fun character. There's a mix of different types of characters in there. I'm one of the ones who gets to have a lot of fun and be an idiot.

MTV: How does the R rating enhance the fun factor?

Forte: It's a completely different situation. There is so much going on in this movie. It's a really fun movie. Adam Sandler has always been one of my comedy idols, so to get to work with him was really fun, and to add into that the R-rated part of this movie, it was so fun. There are very few people who can swear with the style and enunciation of Adam. He just hits them just right. It was so much fun. This movie feels like a throwback to some of the earlier Sandler movies, with the addition of swearing. I cannot tell you how fun this experience was. I feel like when you watch the movie, you can tell how much fun we had.

MTV: How was it working with Vanilla Ice?

Forte: I got to hang out with Vanilla Ice quite a bit. It was awesome. He is so different than I thought he would be. He's this very sweet and loving person, just kind of normal for Vanilla Ice, if that makes sense. He's this wonderful, warm person, but still the Vanilla Ice you want to see. He doesn't disappoint you in not being Vanilla Ice-y enough. He's an awesome guy.

MTV: You have a lot of things on your plate in addition to this movie, like "Rock of Ages," the comedy pilot "Rebounding." What are the odds we'll ever see a "MacGruber" sequel?

Forte: We would love to do a "MacGruber" sequel! I don't know if anyone with any money would love us to do a "MacGruber" sequel, but we talk about it all the time, and we might even — to just get it out of our heads — we might sit down and write a second one. If we could somehow talk somebody into putting some money up for it [that would be great]. We're so proud of that movie and had so much fun doing it. There is no serious talk about making a "MacGruber" sequel, but there's some non-serious talk about it. A couple of the people who were a part of it sit around and get drunk and talk about it; that's the level of talk.

"That's My Boy" opens everywhere June 15.
