How many days did you spend in the water?

Matt: Water movies are really hard. I mean, we were on the water. And it looked like a big army out there. We had the boat that we were shooting on. Our dressing rooms, or where we would get our makeup and change and stuff, was on another boat, and we’d shuttle back and forth. So, it was all boats.

Kate: And then tank.

Did you do the water scenes, or use stunt doubles?

Matt: We pretty much pulled it.

Kate: I mean, I held my breath in one take; I couldn’t for 45 seconds, because I had to go down and then wrap the rope around. When you see it, you’re like, ‘God, they make it look so easy’. 

Matt: Yeah, it’s onscreen for five seconds.

Kate: I was really proud of myself for that stunt because I had been doing long exercises to be able to get myself ready for however far I needed to get to. It was wild. The thing about working in water is that it’s so sensitive.

You really have to be very careful. And everybody has to be very on.  It’s very serious. So, there's not really much goofing around when you're working underwater.

Matt: And Kate came a long way from the day she went out to go get certified, till the end. She came a long way with her comfort with the diving stuff and just being in the natural water.

What is the most beautiful place you've gone diving or the toughest dive that stands out to you?

Matt: While I was there in Australia, I went over to Papua, New Guinea, and dove, and did some wreck dives with some World War II planes and stuff.  That was one of the cooler dives I’ve done. About, I don’t know, 35 to 40 metres. That was really cool. There’s two, either they have a nature dive or a wreck dive. I’ve done nature dives, but that wreck dive was really pretty special.

One of the delightful things about this film was the chemistry that you had, which was nice without being ostentatious.

Kate: Yeah. Without doing a tap dance.

Is that just something that happens organically? You don't know what’s going to happen?

Matt: I think so. I think that’s just something that is good with Kate and I.

Kate: I think it just kind of happened.  The first meeting we ever had when we were going to shoot How to Lose a Guy…  I think everybody in the room was, like, ‘Oh, this is going to be really fun and easy,’ because we just got along really well.

Matt: And we surprised each other on the screen.  I think one of the things that’s cool with Kate and I is that if one of us does surprise the other, the other one doesn’t pop up and yell ‘Cut!’  We kind of roll with it.

Kate: Do people pop up and say ‘Cut’?

Matt: Sometimes.  There were times I’ve said some things that weren’t scripted and someone will go, ‘Wait a minute. That wasn’t in the script.’ 

Kate: That's so funny.

Matt: But a lot of our accidents are the stuff you see on screen.

Kate: That’s true.

Matt, now that you're going to become a father, do you have any second thoughts about doing stunts?

Matt: No, not really.  I mean, look, like in any sport, if you start playing not to get injured, that's when you get injured.

Kate: You’re going to be a daddy. 

Matt: I’ve had some scary situations where I’ve been on films, and on this one in particular I had quite a few, but not to an extent where I regretted something I did. I’m not foolish with it at all. 

Matthew, how are you looking forward to being a dad?

Matt: Oh, it’s been a great adventure. I’ve always wanted to be a father, and was just waiting for the right time. I’m with the right woman, and now it is. So, I’m excited for the new adventure.
