Transcript for Sexy All-Star Cast of 'The Other Woman' on 'GMA'
"The other woman" is a new movie out. About three women who are all betrayed by one man. But this is the good part. Instead of getting angry at each other, they join forces to get revenge. And it stars Cameron Diaz, Leslie Mann, Kate Upton. Joining forces, joining us now. And we have a little sneak peek. So, take a look. Target is moving. Target is on the move. Okay. I can't believe you're not interested in this at all. He's getting up. Oh, my god. What? Did he have that made? When you have a body like that, everything fits you perfectly. A perfect ten, lemon tart, dd, obviously. He is saying, I play tennis. Unless you're John McEnroe, I stand to lose. Tell everybody what you say? I go, I am McEnroe. And we go over the dune after her. And then, I tackle her. Yeah. And, Kate, your character is left to wonder -- What did I do wrong to these two? There is a sort of wonderful joining of forces in a situation that is very difficult. When you read the script, that had to appeal to you. Absolutely. I mean, I think that, you know, we're so inundated with these ideas that women hate one another. And they're competitive. And they have so many examples of that on television, where, you know, there's just women constantly stabbing one another in the back, even when they're supposed to be friends. And this is about three women who are brought together by this weird circumstance of all being involved with the same man. And instead of hating one another and stabbing one another in the back, they put the onus on the man because he was the liar and the cheater. They join forces, basically. They do what women do, which is -- they take care of each other. And they help each other through a hard time. Yeah. They support one another. I couldn't get through hard times in my life without my girlfriends. And that's what these women did. And these women, in real life, supported you, you were saying. This is a big role for you. Yeah. This is my first movie role. And these two supported me every step of the way. They made me feel so safe, from day one. They encouraged me to mess up and try new things. And they were just amazing examples. And she's fearless. I mean, she really -- In a bathing suit. Hers is smaller. Like, the diaper was really hers. I don't even know how mine -- Well, you know. It's funny because when we were filming that scene, you know, when you go to a beach, everyone's wearing bikinis. So, it's pretty Normal. But when you're filming a bikini scene, nobody's wearing a bikini. Only you. And 60 crew members. And 60 crew members. And these two saw that I was feeling a little uncomfortable. Even doing "Sports illustrated"? That's a small crew. That's only like five people on set. And I worked with them so many times. And it's hot there. Everybody's in bikinis. Yeah. But these two came and ran beside me offscreen. And I never had support like that before. And it was so amazing that I got that on my first film experience. That's great to hear. There's a scene that I absolutely love. I was telling you guys. You're stalking -- you're trying to figure out who this third woman is in your man's life. And you're trying to look over a gate. And you fall. And the next thing you know, you have to pretend you're stretching, like you were just on a run. But it's really your legs. That's such comedy. Like, yeah. Just working out. My legs over here. Don't mind me. She's so flexible. So flexible. That would be so hard. Of course, you start off with one leg. And Leslie takes it to two legs. And everything is -- what do I do? I'm laughing. Just trying to be limber. Trying to be limber. And cracks up. It was in the bushes. It's good physical comedy. You can take a fall, girl. You do it a few times. Yeah. It's really fun. The thing that we found with one another is we have this really funny dynamic where, I have really long legs and a short torso comparatively. And she has a really long torso and longer legs. Comparatively, to her torso. She has great gams. We had this funny thing where I'm on stilts like this. And she's really low to the ground, center of gravity. And like, she has eight arms. You don't see them all right now. But she has eight of them. And every time, I'm, like -- In the heels. And I didn't -- I have a feeling this was a fun set. I never want this party to end. So many of our viewers are asking questions. Are you okay with social media? Sure. This is from Facebook. It's from Dina. She wants to know -- wow, I don't know. Dina wants to know if you all have been in this situation? We have not been in this situation. That's an easy answer. Okay. Not that we know of. Yeah. Some things are better left unsaid. You said last week, you were talking about monogamy. And it's in relation to this film. What did you mean by that? Well, my character says she doesn't believe in monogamy. And then, somehow, journalists were, so, you don't believe in monogamy. That is my character. My character said that. Yeah. I'm an actor, right? Exactly. She needs to answer that. You need to answer that. I totally -- You do. Oh. I'm just -- I'm acting. You do that? Glad we straightened that out. Monogamy I think is an important part of relationships working. Absolutely. And so are relationships with women. Absolutely. And in real life and on screen, in "The other woman." It is in theaters everywhere on Friday.
