It figures we'd have the best Jack Black interview ever for a drama. Leave it to JB to turn everything on its head. He's actually the funny part of Margot at the Wedding. The sibling angst story of a sister (Nicole Kidman) disapproving of her sister (Jennifer Jason Leigh)'s fiancé (Black) gives Black ample opportunities for well-timed barbs.

CraveOnline: This is not the first time you've had a mustache in a movie. How long does it take to grow the 'stache?

Jack Black: You're right. Now that you mention it I had a mustache in Nacho Libre. Right now, how long has it been since I've shaved? Only a week. Does that look like a good 'stache? No. I'm about a month, to grow a good substantial mustache, a robust 'stache. Robust.

CraveOnline: Do you get a lot of dramatic offers beyond all the comedy offers I'm sure you get?

Jack Black: I get some cool offers for drama type stuff, but mostly no. Mostly it's comedies and I'm not going to get paid to do drama any time soon. I do it for the love of the game. In this case it was the director. I really wanted to work with Noah [Baumbach]. I really loved The Squid and the Whale. I'll do some more movies for free if they're good too. I'm warning you. So consider yourself duly warned.

CraveOnline: How do you make yourself cry for those emotional scenes?

Jack Black: You just try to be open and think about what if this was really happening. I like to do the "what if" exercise. You just say to yourself, right before they start filming, "Okay, what if this was real? What if this was really happening?" I try to go with that.

CraveOnline: You don't have a traumatic memory from your past that you pull up?

Jack Black: I don't. That never works for me. It always backfires. When I cry the easiest is when I'm in the movies, if I let myself. If there's something emotional I'm a sucker for the cheese. If the cheesy strings come up and the underdog does the impossible and he feels good, I'll start.

CraveOnline: Do you have to hit a comedy mute button when you're doing a dramatic role?

Jack Black: Yeah, for sure. I mean, it also helps that the writing is so good and also not messing around with the script at all. I'm not improvising at all in this movie and so that's usually when the comedy wheels will really start spinning, when I start improvising. I had to keep it more real.

CraveOnline: Was the nude scene in the script?

Jack Black: It was in the script. That was one of the things that when I read I was like, "Really? F***. Alright, I'll do it anyway despite that." I've shown a lot of my ass in movies past, but never the whole ass. Never a drama ass. This was a full moon.

CraveOnline: Has it piqued your interest in doing more nude scenes in movies?

Jack Black: I'm going to be doing pretty much all hardcore pornography. This is a gateway to that.

CraveOnline: Did your character in this remind you of anyone that you know or did you identify with a guy of that age who was still struggling?

Jack Black: Yeah. He did remind me of a couple of people that I thought about when I was doing it. I mean, I know a lot of people or struggling artists that didn't catch the train, really talented people. You see them around all the time that for one reason or another, and it's easy to imagine myself having not gotten the lucky career that I've had. But when I tried to do it in the voice of specific people I knew it kind of went flat. I'm better at just being in my own voice and imagining myself in that situation.

CraveOnline: You've been pretty successful from a relatively young age. How do you think you've been able to tap into these guys when you haven't really been that guy?

Jack Black: Well, because I wasn't really that successful from a young age. I got a part when I was in my twenties, but for the most part I struggled through the twenties and it wasn't until I was thirty that I kind of got my career going. Throughout my twenties I saw all these other people skyrocketing up all around me. So I know how that is.

CraveOnline: Where were your ambitions during that time?

Jack Black: I always wanted to be an actor or a musician. I wasn't bitter though. I was still young enough. In your twenties you don't have to accomplish anything. I didn't feel that pressure so much. I was just like kind of having fun and if I had to go back and live at my mom's it wasn't that big of a deal. I didn't think of it as that huge of a failure. If I had to go back there now at thirty eight then it would be a crushing blow.

CraveOnline: What was it like singing What's New Pussycat in Korean for The Simpsons?

Jack Black: That was fun. You saw that? I'm bummed because I set my Tivo to record it and I didn't put a minute later and it cut off the credits and I knew that my singing was in the credits and I wanted to listen to myself to see how it came out.

CraveOnline: They always put out soundtracks for The Simpsons so when there's enough songs, you'll be on the next one.

Jack Black: I hope so.

CraveOnline: What's next for The D?

Jack Black: I love The D and the music. We're writing new songs for the big massive comeback masterpiece album. It should be powerful. I really love the first two albums even though the second album didn't make as much as the first one. I don't want the quality to go down for number three. So look for that around, I don't know, 2012.

CraveOnline: You've got a track on the new Guitar Hero. How cool is that and what do you think of that phenomenon as a music game?

Jack Black: Yeah. It's great. I have to get it. I want to play it. It's kind of cool. It's a fun game, but it doesn't really have anything to do with playing guitar. You can be really good at playing that game and horrible at playing guitar.

CraveOnline: How has fatherhood been in the last year and a half?

Jack Black: Good. It's very rewarding. A beautiful babe. He's such a handful. Sometimes I'm just sort of wishing that I wasn't working so much so that I would have more time to hang with him.

CraveOnline: Have you seen the milestones like first steps and first words?

Jack Black: Well, they say that the first steps are so incredible to see, but they came and I was like, "Was that a step? It was more like a fall." But there were some steps on the way to the fall. He's really good at that stuff and he's been talking for a while, but not really. He doesn't grasp language yet. There's some words in there, but there are no sentences. There's a lot of gibberish. It looks like he's really talking. I can't tell though. It's like, "Do you think you're saying something or are you just pretending to talk?"

CraveOnline: And how is the love life now that you're parents?

Jack Black: It's still good.

CraveOnline: Be Kind Rewind looks amazing. What were some of the most fun movies to remake in that?

Jack Black: I loved doing Ghostbusters, Rush Hour, Driving Miss Daisy, Robocop.

CraveOnline: That's such a high concept, but it's Michel Gondry. Will it be mainstream appeal or more indie?

Jack Black: It's very, very quirky and funny and it could go over well. It might stay in the art-house world. I don't know. I know that when we were making it we were swinging for the fences and having a really good time, but he's an unusual director with a very unorthodox style. So I try not to spend too much time thinking how broad the appeal will be.

CraveOnline: Tropic Thunder is an all star cast too. What was it like working with Tom Cruise?

Jack Black: I did meet him at the read through, but I have not had any scenes with him. I don't have any scenes with him on this movie, but from what I've heard he brings the thunder.

CraveOnline: And your blonde hair is for that?

Jack Black: This is the director's vision. No one is straying from Ben Stiller's vision. He rules with an iron vision stick.
