She knew she wanted to be an actress when she was 3 years old, 30 years later Keira knightley has starred in dozens of movies we have all seen and loved. "Pirates of the caribbean," "Rule actually." "Atonement." Can we sit any closer, by the way? We'll try. In her latest film, "The aftermath," she gets caught up in a post-world war II love triangle. This dress, it isn't right. What you doing? He's downstairs. Just tell him. Tell him you're leaving with me. Tonight. I can't. Then I will. Everybody, please welcome Keira knightley. Nice to see you. Mwah. Thank you. Thank you so much. Well, congratulations on this film. It is beautiful. Very dramatic. Very dramatic, yes. Very emotional. Yes. I understand that it wasn't sometimes for an actress it can be hard to get into that place emotionally. For you it was hard to turn off the waterworks. My daughter was about 18 months old when she were filming this and wasn't sleeping and if you have children and they don't sleep you know that emotions are very close to the surface so it was like every single scene they said you might need to cry, it's fine. Can you just stop crying? No, I can't. You have to thank her when you get your award. Absolutely. She's 3 now, right? Yeah, she is. So that's such a fun age but you made the conscious decision after you had a child, you said I don't want to do nude scenes anymore but there are a couple in this particular film so tell me how that worked. Well, they said, look, we want to do a nude scene and I said, yes, that's guy idea. Are you comfortable. I'm comfortable as long as I don't have to do it. They said, okay, great. So you can choose your own body double. How fun was that? How was that process? It was actually -- I wish I could do it every day when you get up, which body do I want today? Exactly. This very lovely lady is my body. I feel like I've been talking about her so much that I'm sort of -- I'm just the head and actually everybody -- I'm just the head. It was great. We're appreciating all of. You thank you. We were looking back at some of your many magazine covers. I loved one, I don't know if you know this. You were described as so poised and so sweary. Oh, good. Like a good curse word. I like a good curse word. I'm from Long Island. I swear like a sailor. Okay, good, no, I do love a curse word. I'm not swearing now, though so that's impressive. I know. Thank you. Sometimes they just really -- They complete a sentiment kind of perfectly. Perhaps we underit runs in the family. A little bit. My kid, hmm she's only done it twice both times sort of been perfect. Once was the American election and she was again only just over a year and I thought, well, that's amazing to be so kind of politically astute and the other time was when we nearly got into a car crash and, again, I thought well actually that's a perfect point. We were in Italy and came around a corner and, you know, there's another car, a blind bend, my husband slammed on the brakes and my daughter just went, I'm not going to say the word by the way, don't worry but my daughter just went, daddy, is that when you say -- yes, actually, that She knows the context. She can contextualize. Yes. You're raising a lovely daughter, we can tell already. Thank you. It is way back Wednesday. The movie, some of you might remember her from "Bend it like Beckham." Way back in 2002. Thank you. That was a breakout role for you. What do you think about a reboot? A reboot? Or rekick since it was a soccer -- I don't think I can kick with me in it? I don't know. You can get a body double. Yes, I could just be the head again and then a wonderful soccer player could do it. Perfect, all right. I believe that's breaking Hollywood news. Breaking or broken. A bit of both. Is it true you don't love to watch yourself? No. Because we do. Thank you. "Love actually" is one of your -- I know George Stephanopoulos, that's his favorite movie. I've only seen it once. Really? Yeah, I saw it at the premiere and never seen it again. You really should watch. That's what everybody says. There's a film you've never seen. Quite a few but "Pirates 3" I've never seen but, yeah, quite a few I've never seen. Have you seen this film, "The aftermath." I have seen this film. Yes, it's very good. You should go and see it. Yeah. We will. It really is great. Thank you so much. Always so delightful talking to you. Thank you. No swears. Fun. "The aftermath," everybody,
