Bleeding Cool have got some info via Jonathan Ross'(who's wife Jane Goldman is scripting First Class) radio show. Apparently the movie will shoot this summer at London's Pinewood Studios...
The X-Men: First Class production office at Pinewood was opened on May 10th and they have two big sound stages for the shoot. Vaughn and Goldman are already working out of the studio to a large extent.
Mathew Vaughan has worked from Pinewood for both Kick-Ass and Stardust so it makes sense that he would bring his next film there too.
Bleeding Cool have also received this request from the West Michigan From Office confirming that at least part of First Class will be set in Central/South America...
A location scout is seeking out areas with a 1960’s, South-American or Central American island feel for the next X-Men movie, ‘X-Men: First Class.’ In particular, he needs to find café and bar locations, evoking the Argentinian feel of Bariloche, and an Art Deco Cafe or restaurant overlooking a body of water. Additionally, the movie calls for a Miami styled harbor for yachts. If you know of any locations that seem to match a description, please contact our office.
So we know where some of the film will be set, even though it won't actually be filmed there. All we know besides is that James McAvoy has been cast as Professor X, Mathew Vaughan is directing, Jane Goldman is writing and it will focus on, in some capacity, the original team getting together. I wasn't looking forward to this, and am still apprehensive given the story, but Vaghan/Goldman and a certain other CBM called
Kick-Ass have proved to be a great combo, so although McAvoy is a bit of strange choice for Xavier, I'm watching this one with some more interest.
