Since its release into theaters last Friday, Steve Pink’s “Hot Tub Time Machine” has received mixed reviews. But whether it be wittily stupid or stupidly witty, what better way to look at a film than through the eyes of the actors. On February 15, 2010, two of the film’s stars — Craig Robinson (Darryl from “The Office”) and Clark Duke (Dale from “Greek”) — went behind the scenes with the Guardian. Get ready for heavy drinking, menage a troi-ing and barrelling from mountaintops.

The Guardian: What was it like shooting “Hot Tub Time Machine”?

Clark Duke: It was fun, but cold — as you would expect with snow.

Craig Robinson: Yeah, during the three months we were in Vancouver, it was just us and the Australians. The resort looked just like the hotel in “The Shining.” He even broke all the shit in his room!

CD: Hey, we’re in this little bitty town and then someone just kicks your door open while you’re asleep. … I’m not going to lie to you guys, I’ve been drinking a lot.

G: If you could go back in time, would you change things?

CR: Change? You know, I wouldn’t change a thing. Actually, there is one girl I wouldn’t have stopped to talk to …

G: How did you look 20 years ago?

CD: My head was the same size. I almost killed my mother at birth. Ha!

CR: I had that haircut — It was real high. I majored in music. I was a super freshman, all goofy and stupid.

G: Were you guys skiers prior to filming?

CR: They said, “We need you to ski for the movie.” And I said, “I’m black.”

CD: All the other guys knew how, but not us.

CR: The boots are freaking tight! I kept saying, “No, this is too tight!” My toes were all scrunched. By the third day, I made it down the mountain. It would have made great extra footage! I snow-plowed down the mountain, but I made it down.

G: What was your favorite part to film?

CR: There’s a scene where I’m in the hot tub with a young lady — I think about it daily. Jessica Paray is her name. It was very professional — I only got hard three times. Ha!

CD: That was also my favorite part. I was under the water!

G: Was it fun on set?

CD: Oh, yeah, there was a lot of cracking up. There was a lot of “Guys, we have to get to Act Three!”

CR: Look out for “Hot Tub Time Machine 2: Cincinnati.” We ain’t going to screen that one — we’re just going to let it out. Ha!

G: Were there any practical jokes played on set?

CD: There were a lot of impractical jokes.

CR: Yeah, not really practical. They kept improving — one would start and everyone would join in. My door got kicked in!

G: What was it like filming scenes with nudity?

CD: There were one too many dudes involved. Cordry’s ass — man, every time he’s nude on camera, he’s flexing, sometimes making a T. But they put flesh-colored socks over your penis.

CR: They didn’t have any to fit me …

G: Did you guys know each other before?

CD: We met at the table reading. I met Cusack at a dinner before the movie.

CR: Congratulations!

G: There were quite a few smart lines — did you ad-lib any of them?

CR: Chevy Chase got to do whatever he wanted, because he’s Chevy Chase.

CD: The script changes a lot, and eventually we just say, “Fuck the pages!”

CR: Steve Pink is one of the best directors I’ve worked with. We’ll be like, “What if we did this?” And he’s like, “Yeah!” And it’s like, “BAM! It’s in the trailer!”

G: So, Craig, you sing all the time on “The Office,” and your character in this film does as well. Is music your first love?

CR: Music is my first love. I grew up playing in church and at recitals. My band Nasty Delicious plays in the movie, too.

G: Did you have any problems while filming?

CD: Being outside when it’s that cold is rough.

CR: Yeah, I had my first sinus infection.

CD: I had to go to the chiropractor after falling down the mountain.

CR: In the last scene, we had to be in the hot tub for two days, and I was really hungover.

CD: We talk a lot about the guys who aren’t here. … You’re probably thinking, are you guys screwing with us?

CR: That’s what she said.

G: So what’s next for you guys in your careers?

CD: I’ve got this new movie called “Kick Ass” that’s coming out, plus a film called “1,000 Words” with Eddie Murphy.

CR: I’ve got “Shrek 4,” “Father of Invention” with Kevin Spacey, and I’m doing more of “The Office” and touring with my band.

G: Why should people see this movie?

CD: It’s … funny?
