Transcript for Matt Dillon Shares Character's Tales of Espionage on 'GMA'
We're here with matt dillon. Hard to believe it's been 15 years since we found out there was something funny about him. Yeah. You get the reference, I hope. Now, he's got some new comedy chops on display again. It's called "girl most likely," co-starring kristen wiig, as a girl who moves back in with her mom, played by annette bening. And a surprising character, played by matt dillon. Take a look. This is my boyfriend. He lives with us. Hi. Pleasure to finally meet you. George. Your name is george bush? Well, as a matter of fact, that's not my name. You see, my father was an assassin. He had to change all of our birth names. Matt dillon here to talk about george bush. The bush. I'm not really at liberty to talk about it too much. Cia. This character has to are have been a blast for you. Yeah. It was a lot of fun. We had a really good time with it. He's a character who is really nothing is what it seems with george. Right. Comfortable in a kimono. Yeah. And you actually had a big say in what george wore, i understand. You wanted to asset the character in that way? Definitely. Kimonos. A gie, that sort of thing. This is guy where nothing is what it seems with george. You know, he supposedly was in the cia. But he's not really at liberty to talk about it. All he does. He has a coffee cup with cia across it. We had kristen wiig on yesterday. And she said working with annette bening was the highlight of her career. Let me ask you, what was the experience like working not only with annette but also with kristen. It was great. It was about a week's worth of work. Yeah. It was really kind of quick for me. Annette was great. Really fun. She jumped into this character. She became this "jersey shore," kind of wacky character. You know, degenerate gambler. Unlike her lover. But I like that about it because it's kind of wacky family dynamic with these people. Yeah. You get that feel. And it looked like you were having a blast, sort of just going for it in the role. I was reading in the notes that you also stayed in character -- we did a lot of improvisation, you know, between stuff. And yeah. It was fun because nothing is like it seems with this character, was kind of fun. I can make stuff up as it goes along. This guy has these complicated rules about what he can talk about, what he can't talk about. George bush, a character for the ages. He's not at liberty to tell you his real name. We may never find out. We'll try, though. Great to see you. I understand you haven't been here since "crash,". I guess. Please, come back sooner. It's nice to see you. Matt dillon, "girl most likely," opens this friday. Thanks for being here. And there's more.
