Stiller directed this movie about a mild-mannered photo editor, who taps into his dreams to capture the girl of his dreams, played by kristen wiig. What are you doing this weekend? Let's see. I bathed in arctic mountain water. I'm walter. Cheryl, milhous. Where have you been? I'd like to climb your hair and test that out. Perhaps I could contact you. Possibly through my poetry falcon. I like that. And I love this movie. It's so beautiful. And it's so charming. You've been busy. Ben, around the world promoting this. Let me get a look, paris, berlin, rome, london, australia. And, kristen, you've been doing double-duty with "anchorman 2." Do you know where you are right now? Are we in china? It's new york city. Good morning. Sorry. This is a very ambitious undertaking for you, ben. You're directing and starring in it, as well. You shot it in iceland. And I understand you even got into the water. Yes. The very frigid temperatures. Yeah. There's sequences that happen in the ocean there. We wanted to get the real seas. There's a great white shark there. That's not actually -- that's a mako. It's a trained mako. Thank god. Just happened to be there, that shark. How cold was that water? About 40 degrees. You know, you have a dry suit you put on underneath. Once your head gets wet, though. You're done? Yeah. At least it gives you a little bit of energy, as an actor. A little bit. Yeah. I'm curious. What did you most identify with, with this character? I just love the idea of someone who lives inside their head and has all this potential inside that nobody sees. I think there's a lot of people in the world that nobody really notices on the outside. But inside, they're incredible. And that idea of sort of trying to get in touch with your potential and be the best possible version of yourself. And, kristen, you did this as an actress, too. Everyone identifies you with "saturday night live" and "bridesm "bridesmaids." And the comedic side of you, you're hilarious. Everything that comes out of your mouth, you start laughing. That's a lot of pressure. You had a dramatic role and it's a big twist for you. Be funny. Be funny and dramatic at the same time, go. I just start sweating. I'm grateful that ben, you know, thought of me because it's not something typically I would have done. But I like doing dramatic stuff. People see you as one thing, i think, sometimes. And you know, you want to be able to branch out. How did it feel, watching it back? Great. I love this movie. I've seen it I think four times now. I loved it, too. It was interesting. We were teasing you. You have two different love interests. They're both here, a little awkward for you. Ben here. And steve carell here. You're juggling two leading men. You're the woman they're fighting over. Yeah. It happens all the time. It was happening backstage. I was happy to be part of the "anchorman 2" rollout in a small way. In any way. To be attached to the publicity of it all. And you said this movie really spoke to you deeply because everyone has secret fantasies of what they -- wish they could be. You two have -- the opposite of dull lives. Is there something -- is there secret fantasies you have to live out? Share with us your secret fantasies. I'm going to tell you, right here. Okay. On national television. They all involve kristen. For me, you know, as a kid, i just wanted to be a movie director, ever since I was 9 or 10 years old. Being able to do this and do what I love doing is totally -- it's my not secret fantasy. And you're not sharing? I will say that I think it's important to have a fantasy life. And everyone has one. Everyone goes to different places in their head. At least I do. I always loved the beastie boys. And I got to go on stage with the beastie boys five years ago at a concert. It's the beastie boys. Great. You could have gone, also. I got to go up on stage and do a song with them. I'm even more impressed now. Thank you for being with us. Everyone should see it. It's a sweet story about what a guy will do to win a date with the girl of his dreams. Thank you. Even if it takes going to iceland and greenland. "The secret life of walter mitty" opens up christmas day, nationwide.
