@Captain Craig it was reported earlier they were thinking about shooting in Vancouver. There was a discussion about this in one of these threads. Also remember (as you seem to forget) that Fox still has the FF and Daredevil reboots to schedule for next year or 2014. David Slade promised there would be news last month but so far nothing. I still anticipate a late 2013 scheduling for "Daredevil" and or early 2014. I foresee the FF reboot scheduled for 2014 along with First Class 2.
@Captaindemotion...Mangold has long been confirmed dude. The script has already gone through a couple of re-writes but most of McQuarrie's original is still in tact. I believe there was an interview some where. Casting can happen relatively fast as we saw with "Man of Steel". I believe casting for all the major characters was done over a couple of month period. Or at least that is when we heard about it.
