Transcript for Behind the scenes of how 'DuckTales' reboot was created
And finally tonight, we all have our favorite duck tales character. Some love Huey or Dewey or uncle scrooge. My personal favorite, ABC's Nick watt. ??? Duck tales ??? ??? whoo ooh ??? Reporter: Duc tales then. Tell me you're bringing back the theme tune. Oh, yeah. ??? Duck tales whoo ooh ??? Reporter: Duck tales now. And this is how they make it. Who plays who? How dare you? They're Dewey and Huey. Unlikely. Reporter: Dr. Who Dave tenant plays scrooge. It's a time machine! The first time that scrooge mcduck has ever been played by an actual scotsman. Reporter: Lin-manuel Miranda is gizmo duck. There is plenty shouting in the writers room. The future louie could be very bitter toward scrooge. Just because he didn't -- this scrooge is still alive. Reporter: Is it always like this or you're just overexcited because strangers are here? No. Reporter: It's always like this? Calm precision from the art director. Here's how he looks to the audience. Here's how he looks to us. He has to look consistent through the whole show and there are tons of people who work on it. This is a model sheet of Donald. Reporter: And time-consuming tweaking in animation and editing. The characters look like that and then we change it so they can be a little more on model. The way they drew his mouth is incorrect. They drew a mouth in front of his beak. Reporter: These oversized children are executive producer and head writer. Buck stops with them. Our main goal is to give kids today the feeling that we had. It really is created with a lot of love. Reporter: They gave me some groans and a line. Egyptian episode. Episode 109. Right. But if we attack tothra and he tells us to surrender we should do that, right? That was perfect. What? That was amazing. Oh, my goodness. Your contempt for my country really comes off. Reporter: Do not judge "Duck tales" reboot on my American accent. It's better than that. Keeping the spirit but mildly updated. I'm Nick watt for "Nightline," Burbank, California. Nice work, Nick. "Duck tales" is produced by our parent company, Disney.
