Transcript for Stars of 'Miss Peregrine's Home for Peculiar Children'
Butterfield, Eva green and Ella pump necessary from Tim Burton's new movie "Miss peregrine's home for peculiar children." We'll tell you about that bed of nails but first a clip from the movie so take a look. Peculiars have been persecuted through the ages. Hence, we live in places like this. I'm a type of peculiar called an ingrain. You turn into a bird. Well, I do. Yes. But that's not very useful and their main skill can the manipulation of time. We choose a safe place, a safe day and create a loop. What do you mean. A loop reserves the last 24 hours, reset the loop and the day is yours to live in again. Eva, you're so good and I love the description of Tim Burton. Tim Burton calls your character scary poppins but I wonder did you get a maternal feeling with all the young co-stars running around. Yeah, of course, she can be quite tough. She's very strict. She has lots of rules, but she has a big heart, you know, and those -- my character has to look after those gorgeous children who had those weird abilities and, yeah, she's very maternal. Very maternal and, Ella, I know you have a cool superpower. Uh-huh. You don't weigh anything. Huh-uh. You can control air but you have to wear these boots and it looks so -- they're heavy. They're uncomfortable. Yeah, I'm glad I look that way. You get used to them I guess after six months, slightly weighted. But I guess the hardest part was the floating, yeah, and the underwater stuff. Underwater -- speaking of underwater you did your own stunts. Yes. And you were champs to do this but underwater -- how hard is it to be underwater with no contacts? Tricky. We're in this tank and paint all the walls of the tank green so you have no sense of depth anyway in this big green space and you can kind of make out where the other person is just vaguely blew the blurry water. Have to keep your eyes open the entire time. What kind of training do you do for that? No, I couldn't swim before I did this movie. I think that's a little dangerous. No, I learned -- I can swim I just sort of drown and so I had to practice swimming but we did a couple of days of diving tra training and got used to the masks. You had Asa there. He would have been the hero in "Step up." Here's a question. Both: What's your peculiar talent? Their peculiar talent is to be really cute and do a spin so, Eva, what is your peculiar talent. Well, I can make myself invisible. Really. Yeah, I can and I'm not going to do it right away but I can. You're so good. You did it and came back. We didn't even see it. And Ella, your talent? Take your pick. I can do weird things with my eyes. Sorry if that freaked anyone out. You can't swim but can you do that. Uh-huh. That's a good one and Asa, what about you? I got various kind of useless peculiar talents. I can type the alphabet fast, in under two seconds, in fact. Really. You have to take my word for it. We want to get this in. We have this bed of nails and I think you'll do something with this. You're the man. And these are real, people. I guess. This is what we do, right? I need to help you. I'm in your hands this time. Don't drop me. This is like -- okay, you have a friendship thing here. All right. I guess we just kind of -- we go down like this whoo. Not too bad. Holy -- whoo. That's not too bad. Not too bad. That's not too bad.
