[Morphindel]

Anyone in the UK (or elsewhere)have an address for upcoming British film adaption of 'Swallows and amazons' Starring Gwendoline Christie, Kelly MacDonald, Jessica Hynes, Rafe Spall, Andrew Scott, Harry Enfield etc?

As of June 25th the news about the location was:

The production is scheduled to move to Yorkshire after location filming on and around Coniston Water and Derwentwater

But thats as much as i can find. I think they have already started (possibly finished) shooting in Yorkshire. I'd be grateful if anyone can get me a reliable address to try as Christie and MacDonald i've been after for years (and i stupidly didnt realise MacDonald was working on Ricky Gervais' Special Correspondents which i did have the address for).

Film is being produced by the BFI and Harbour Pictures. Can anyone help me dig a little deeper? I have a trial Imdb Pro account in my inbox, but would it have the production addresses on there?
