Transcript for Will Arnett on his new movie 'The Lego Movie 2: The Second Part'
Preparation H. Get comfortable with it. Will Arnett may be my favorite big-screen "Dark knight" as Lego Batman, and he's back in the new sequel, "The Lego movie 2: The second part." Please welcome the fabulous will Arnett. ??? I couldn't hear it but it sounds like that was my music. I feel like you're the only person who's been here this week that's not running for president. Well, I too have an announcement to make. I am not running for anything. Good. Right, doesn't that sound good? That sounds good, yeah. Nice pallet cleanser, I like that. A little bird told me that you just came back from London. Yes. And you're pretty tight with prince Harry. Is that true? Well, I don't know about tight. I mean, he seeks my counsel a lot, sure. No, no, I got to know him a little bit. He's such a cool guy. Actually, the last time I was there I texted him as I was walking by Buckingham palace, I said I'm in town and was just thinking of you. I was just walking by your gran's house. I thought it was cute. Did he respond? Whoopi likes it too. I'm smiling. Did he respond? He did not respond. But the good thing is I cleared with British security and I'm fine. Okay, good. It's probably in his junk. Junk mail. That took me a second, whoopi. It took me -- it's Friday. I'm not used to talking. I don't know if he texts from there. Anyway, you're my favorite Batman. You're the only Batman I like. And I hear that you brought us something from the world in which you have been inhabiting. I did. I brought you a little something from the lego-verse if you will. Check it out. It's somewhere here. There it is right there. Is that supposed to be us? It's y'all. You don't want to mess with that crew. Really take it in. I really like my outfit, so thank you, lego-verse. And I'm wearing vertical stripes which makes me look thin. That's smart. I look like me. It doesn't matter what you do, I always look like me. So why isn't Lego Batman in that shot? Because I won't share a set with other people. I see. No, there wasn't enough room because Batman, he's got a pretty big -- he's got a big ego, you know. He should run for president. Maybe he should. There's a lot of big egos running for president already, baby. Tiffany haddish plays a character in the movie and you can say she's your love interest maybe. Can we take a look? Listen lady, don't try any mind games. Batman is a permanent bat-chelor. Can you imagine if having a family with someone I loved healed some of my darkest drama? Barf. There's no way I'm marrying you. I was just saying that to make the person I actually want to marry jealous. Good, so I guess we're done here or? Marry Batman, that's a good one. You funny. Tiffany -- Tiffany, she claims that you're her mother so -- She does. Whoopi's not old enough to be her mother. I actually am. I know. Yeah, I know, I like her so much. She's lots of fun. She's lots of fun. She's so much fun. She's so surprising which is a great quality. All right, can we stay with this romantic mood for a moment because your voice, your Batman voice, I can listen to it all day long. Okay. You couldn't afford to. You guys were having fun. You should do an app on a phone so people, whenever they want to hear it, they can listen. That's a great idea. Maybe make some money. We want you to read some of the most iconic romantic lines in your infamous Batman voice. You had me at hello. That's good. That's a good one. I'm aroused. Oh, my god. And that ain't easy. That ain't easy. My god! What else? I wish I knew how to quit you. That one, I know the source of "Noting hill"? No. I think we should do a segment, what movies has whoopi seen? We're going to watch another clip though. You, your Lego 2 movie, takes place in a galaxy far, far away. Yeah. And James corden took you to space camp. Yes. To see which of you would be the best astronaut. Yeah. I am dying to go to space camp. I've been to space camp twice, everybody. Let's watch the clip. Good luck, will. Good luck. All right, that's not Normal. You let me know when you're ready for the questions. I'm ready, man. Who was the best Batman? Michael Keaton. If you had been the first man on the moon, what would you have said? Bro. Full stop. What can you tell us about Uranus. It's never been explored. There it is. Well done, will. That was -- That's amazing. That didn't feel good. That didn't feel good. Did you puke? You liked it better than this, than the one that was going around that way? I liked that less. Doing that -- Did you go to Huntsville? Yeah. Amazing. It's really fun. I actually -- they said Elizabeth banks won. I don't know, I'm looking for a recount on that. Probably because I almost -- I almost barfed. Let it all go. Yeah, yeah. Well, now you know how women feel. That's true. They're like that for nine months, some of them. Tell me about it. They say hello and it's -- you know, you don't get to come here often enough and we really like having you so please come back again soon. I would love to. I love being here.
