Transcript for 'Suicide Squad': Cast Plays 'Secrets Behind the Squad' on 'GMA'
Hey, Angelo, this is the exterminator you called for your rat problem. Account is look a little thin. No one gets paid until what needs to get done is done. No money, no honey. There he is. Will smith in "Suicide squad" and they're back. I have to start with you, Joel. I noticed something on your arm. It says sw ad. How many of you got the tattoo? Statistically -- Yeah, I was covered if scales. Seriously. They're on their ankles. It's something else. And obviously -- I did that one. You made that one? Yeah, that's mine. You can tell. You're going to remember that. I believe we have established that this is a fun crew to be on set with. So why don't we find out a little secret behind the squad. A little more digging, shall we? Yes. Really want to go there? I'm not scared. All right. Let's start with you, a lot of people, are going to see you in the croc suit and think that's cgi. Set us straight. It is or isn't. Well, I can testify five hours. Not cgi. No, we had an amazing aesthetic team headed by Chris Neilson and David, the director was insistent on not making this character cgi because he wanted an actor to bring the soul of the character out. Wow. So we spent five hours a day, you know, sometimes depending on the angle shooting, sometimes three hours but maximum was five. They would spray paint it wear it for 12, two hours to take off. And look what we got. Look what you got. Took it seriously too. He actually ate an actual person to prepare for the role. We thought that was real actor commitment. Yeah. That was method. He's croc. He's accountable. What can I say. Jai, your eyebrows are coming in nicely. Don't they look good. Quite nicely. Not as nice as this woman right here. Queen of the brows. I have clippings and I attached this emto my eyebrows. You shaved your eyebrows for the movie. I did. My goodness. I looked like crow magnum -- quite pronounced brow for a number of months. I think it works. What people don't realize when you do things like that for a role like we first saw him, we were like, yeah, we're going to be committed to this and jai came in and his eyebrows were shaved. We were like, ooh. Ooh. Because you ever see when a dog gets freshly shaved. That's how I walked into the room just like with my tail tucked. Right. Hey. When you do that, you shave them and see them in the movie but while we were shooting on the weekends at the club, his eyebrows were shaved. It doesn't end there. It doesn't end there for six months. Buy a drink for that sad guy over there. I was apparently emotionless. It works for you. Margo, this is your second movie with Mr. Will smith. Can you tell us a secret about will smith that we don't know. Hmm. A secret about will. No, she can't. He -- when we first met, will didn't know how to swim. Ooh. You have taught him. I was insistent that he get in a pool. He still doesn't know how to swim. Right. He took lessons. He did lessons. Listen, I grew in the city of philly. There wasn't a lot of swimming pools. For an Australian to hear that, that's the crazest thing I've ever heard. Get in a pool. I'm going to learn. A black man, we don't swim. Right. I didn't want to be the one to say it. We don't swim. Not a lot of swimming. Do you? I know how to swim. I didn't want to say that. I didn't. We could go on and on. Thank you so much for coming and having so much fun. "Suicide squad" hits theaters. And coming up we have more
