Robin roberts and -- the lovely kate hudson. You're right about that, sam, sees her taking on an emotionally-charged role. She plays a grieves artist who embarks in a relationship with a young pakistani man just before the september 11th attacks. The story chronicles the impact it has on their relationship and their lives. We are delighted. Please welcome, the beautiful, the talented, kate hudson here to "good morning america." Thank you. You had a late night? I had a late night. Whoa. I had a late night. The screening went -- our q&a went to 12:30 or something. You're a troope and you get up. I have a beautiful life. I have a baby. So, you know what it's like. I watched it over the weekend, with my friends. So provocative. So thought-provoking. It was -- it looked like a different role for you. Yeah. It was different. It was one of those things, i went, absolutely. I don't get opportunities to play parts like this as often as sometimes I hope. And to work with somebody like mira, who is such an incredible talent, it was a bit of -- it was a no-brainer. And the film ended up being very powerful. She did an amazing job with a very difficult subject matter, using 9/11 as a sort of political, you know, backdrop to incorporating some very big themes. I have to say, watching it, because of what happened in boston, with the bombings there last week, you view it -- the timing of the film coming out -- it is resting. And I think that, you know, the thing that mira's done with this is sort of used the word funn fundamentalist as a way to use that word. Strip everything down to black and white. And you use all sense of empathy, human connection, no understanding of human suffering. And she tells a story about a young man who is searching for those things. Searching for what it is to connect. And she just -- I mean, it really is a fascinating movie. I hope people see it because it's really interesting. It's thought-provoking. A real conversation piece. It does. Let's show a piece of it. "The reluctant fundamentalist." Do you ever think about kids? I did before. But the world's a little scarier now. I'm not as sure as I used to be. My parents never said it out loud. But I know they want two things in life. They want security in their old age. And they want grandchildren. And you want to give that to them? Yeah. They're my parents. And fulfill your duty. I saw youn the screen, with brunette. That reallyped with the role, changing your color. I think, too, mira wanted it to be richer in tone. Just the tone of it. And I think it would be wrong to a baby. I did. Being with a 2-month-old. I was breast-feeding, you know? And bawling my eyes out. A very emotional chacter. I went from, you know, being mommy to -- mira was amazing. When you work with a female director at a time like this, she was rubbing my feet. Just, going -- only she could get me to do that at that time. I know your mom, goldie hawn, has given you great advice on that. But you want to have a little fun. I do. Give us the first thing that comes to mind. Uh-oh. What song makes you happy every time you hear it? Oh. I have a couple. I'm going old-school. "Good day sunshine." I love it. The other one would be the fun song because my son loves that song. "Tonight." "Tonight." And then, I'd say, I have to go with a muse song. Your fiance. What movie can you see over and over again? "Jerry maguire." Ooh. Nice. And what is the worst fashion trend you ever bought into? Ooh. Flats. They're not good on me. But I wear them. I just don't like flats. But I go and walk in heels. Those are great shoes. Other fashion trend I would say would be -- you're really into this. I like this. You're thinking. I can't help it fashion, fashion trend I bought into it. It's great because -- aren't you with ann taylor? Yeah. You have a line coming out. I do. I have a collection with them. We did a collaboration. It was really fun. They're great there. That company's amazing. They do amazing things for women. And I'm really happy to be a part of that brand. Great. It's so good to have you here. Continued success. And "the reluctant fundamentalist" opens this friday in cities nationwide.
