JF:  It was amazing wasn't it, Gemma?

GA:  Oh, we loved it there.

- How much filming did you do at sea and what was it like?

GA:  Well, I didn't do any.

JF:  You did looking over.

GA:  I was looking over and because they used a lot of water tanks but I wasn't involved in any of that.  They actually built a boat which they used and had all of the crashing waves.  And the sea stuff was in Tenerife as well with beautiful cliffs.

JF: I think geographically, our Clash of the Titans using Tenerife was really iconic.

GA:  Tenerife and Wales. They used beautiful beaches in Wales.

JF:  Amazing.

GA:  Beautiful.

- Of the different amazing locations, which was the toughest shoot for you both?

GA:  Wales.

- Why?

GA:  It was cold and wet and it rained.  We filmed there in July.

JF:  It rained for 28 days.

GA:  Yeah, it was just solid rain, rain, rain.  That is where we filmed the scene before we go into the underworld, before Medusa's lair there's and all this load of gray slate.

JF:  That's sort of the slate mines and that's an original slate quarry.  It's incredible.  It's amazing looking.

GA:  It films beautifully but when you're there it's just gray and rain and it was really cold and I was thinking “gosh, it's July, it should be warm and I was laying down most of the time in this kind of nighty-type dress, absolutely freezing while they were kicking butt.

JF:  They did a shot where they took me up in a helicopter, and left me on the top of a hill by this quarry.  It's actually a mountain.  They took me to the top of it, they left me on the top of the hill on some rocks and then they flew off and they were going to fly past in the camera to film me.  And I've got the full thing on like that. 

And I was standing there thinking, "Blimey, that's a bit quiet up here." As I was standing there, two climbers walked past me and they were like, 'All right?.' 'I’m making a film.'  And they were like, 'Really?' 'Yeah, yeah, I'm just an actor making a film.' 

And they were just completely flabbergasted by this sort of monster on top of a rock with no one around and the next minute the helicopter came past.

GA:  How surreal for them.

JF:  Yeah, they were like, "You're never going to guess what I saw when I was climbing."

- Can you talk about the fight scenes?

JF:  I've got these wrists, so there's not a great call for me getting asked to do lots of warrior parts, but Clash of the Titans was great because I got to fight loads and loads of guys.

I was kind of handicapped by the fact I had a club foot and rock as an arm but it was great fun.

GA: The final fight is brilliant, that fight between you and Perseus.

Clash of the Titans is out on DVD 26th July
