"It's an explosive conclusion to the Doctor's New York story." "But going out on a high wasn't easy." "Join Confidential as we strip the Big Apple to its core and show you how the Doctor Who team made Manhattan." "It's hard to do 1930s New York in Cardiff, let's be honest." "The big challenge in the episode was making it feel authentic, and making it feel like New York, so obviously to go over there and shoot plate shots and be able to blend the real New York with bits of Cardiff, it makes that episode" "just feel that bit more epic." "It's actually easy to go get a shot of the real city, where the shape of the city, the grids and the angles you need to see it from actually exists, then paint that picture to look like the 1930s." "So we ended up sending an effects crew and the director, James Strong, and Confidential over to New York, where they got the right angles." "They just got beautiful, clean shots of the Statue of Liberty, shots of Central Park, that sort of stuff." "It's like Doctor Who, in New York, in 1930." "Brilliant." "It's ambitious to set a story in New York." "It's deliberately ambitious, and I didn't know how far we could go." "But again, with this design team and this effects team, you set something rolling and off they go, they grab it, they run with it." "NARRATOR"." "Traveling stateside, the Doctor Who production team are in Manhattan to marvel at the New York skyline." "Certain that if they can make it there, they can make it anywhere." "Do you want to leave that building in the background just black'?" " Which one'?" " Well, I don't know if you want it..." " No, see the smoke that's against..." " Oh, yeah." "Absolutely." "Yeah." "We've come to Central Park, which is kind of where we're saying where Hooverville was based at the time, and so we've..." "Obviously, it's not here anymore, so we've had to shoot plates of Central Park and buildings." "If you look around, the kind of period buildings, a lot of which haven't changed since the '30s." "And we're gonna construct a kind of collage, if you like." "Essentially, we're painting out the modern buildings and leaving the '30s buildings and then adding the Empire State Building into the shots." "Most important thing about today is kind of getting the buildings coming up out of the trees." "So, we've got to be quite specific about which places we've picked to film our plate shots today." "We want the trees so that we can kind of cut around them and put the Cardiff trees in, essentially." "Some of the foreground buildings are period, so we'll cut those out along with the tree line." "And you can do that, what, because they're straight lines'?" " So you can quite easily cut them out." " Yeah, very easy to cut out." " Okay." " I mean, we'll use the tree line, wherever we film, we're gonna film in Cardiff at a park, we'll paint these trees and these period buildings in." "Behind me is the beautiful Sheep Meadow of Central Park." "So, actually, we'll have all of our action taking place and the Doctor and Martha walking through, and it'll look like it's part of this massive landscape behind us." "It's gonna work, Dave, isn't it'?" "Tell me it'll work." "We're gonna put the Tardis right the way in the middle of the lawn in Cardiff." "And then it's gonna be magically put here, in front of the Statue of Liberty." "Because we only have a limited number of special effects shots, we have had to find a piece of wall up in Cardiff which matches the base of the Statue." "We'll film David and Freema against green screens, and then put them in, and when we're finished, it'll look like the Tardis really has landed here." "Manhattan's over there, the most beautiful view on a really gorgeous sunny day." "I'm sitting here thinking how are we gonna match this in Cardiff in November'?" "But, hey." "We need a lot of luck." "But luck was on their side, in a small town called Pennaf, and the Welsh weather is perfect." "We're a month later now." "It's a month since we shot those plate shots in New York, and the weather is exactly the same today as it was that day." "It's kind of gobsmacking because it's been raining for two weeks here." "This is actually a fantastic match for the base of the Statue of Liberty." "The brick on the wall here is almost identical." "We looked at every piece of wall and brick in Cardiff, really, to find this, and then there's the grass in front, and so when we jump back and paste this into the real plate shots of the Statue of Liberty," "it's gonna be a fantastically easy match." "And action." "Anywhere else in the universe, I might worry about them." "But New York'?" "That's what this city's good at." "Give me your tired, your poor, your huddled masses and maybe the odd Pig Slave-Dalek mutant hybrid, too." " The pig and the showgirl!" " The pig and the showgirl." "Just proves it, I suppose." "There's someone for everyone." "There's a bit of ill feeling around this morning because everybody's really annoyed that we got to go to the real place and here they are in Cardiff, trying to recreate the magic of New York." "Sorry!" "Sorry!" "Can I just point out our lovely producer, Phil, and our director, James, and our visual effects man, Dave, and some of the Doctor Who Confidential crew, all got on a nice weekend in Manhattan." "We are in a car park at the Pennaf Leisure Centre." "Draw your own conclusion." "That was James." "And a local dog just wee-ed on the Tardis." "To make matters worse, we've got a mix-in overlay monitor with all our plate shots of the real Statue of Liberty." "We put our actors against green screen and then we put the real view behind it." "So it looks like they're really standing and looking out over Manhattan." "All the stuff we shot with David and Freema today will match exactly what we shot in New York, so it couldn't be better, it couldn't be more perfect, it's brilliant." "Our sets tend to fall into two categories." "Sets that we build from scratch and, you know, that the carpenters build and set decorators paint the walls of and install the electricity into, etc." "Or locations that we go to and transform into something, and that's the perfect example of that." "Back at Bute Park, home to Hooverville, there's a charged atmosphere for what promises to be a very explosive night ahead." "This is called a quick det cord." "It's a highly explosive igniter cord." "But what we do is, we wrap it round petrol and when it goes off, it just creates a really clean, nice, big fireball." "Like any high explosive, it obviously sends a shockwave and it's very dangerous." "The secret of special effects is timing." "Now, this back mortar box is gonna be a big ball of flame." "Angled straight up." "No, no, no, we're going to build some fire up." " Okay." " With petrol." "Firing straight up in the air, debris pushing towards that camera over there." " Okay." " And over there as well." "All right'?" "And as well as that, we've got this shed, which is just gonna blow outwards." "There may be a fireball behind it as well, timed in, so it looks like the explosion pushed it forward." "Guy's gonna be starting about here." "So on action, Guy's gonna be running, running, running." "Kim and Anthony can take their own timing, soon as Guy's on here, bounces up." " Then I'm gonna hit the button." " Danny, you det then, yeah'?" "Camera's gonna be here." "Explosions there." " And the Daleks up in the sky." " Yeah." "And then our stuntmen will fly towards us." "So we'll have yours locked off, obviously." "And then we'll have two other cameras on it..." " Yeah." " ...elsewhere, getting the full..." "You see Daleks in the sky." "Ready!" "The humans will surrender!" "Okay!" "Okay, fire's out." "Everybody stay where they are." "It was brilliant." "That went bang, didn't it'?" "I'm happy with that." "That was good." "Very good." "Thankfully the weather's been great, so it's been a clear night and it's gone all right so far." "We've got all the explosion stuff out of the way and it went really well." "Cardiff and New York have been on an exchange like no other." "And for two episodes, the Doctor Who team have faced extraordinary challenges bringing the Big Apple to the small screen." "I'm incredibly pleased with the way they turned out." "I think they do look epic." "I think you feel as if you're in New York and I think you feel as if you're in a world unlike any other that we've visited." "It's just real." "You think, "My God!" "They're really there."" "It's lovely, really lovely."
