There is reported back to back and there is the real production schedules of neighbouring films. These calendar details are usually ironed out months if not more before big productions go into production.Good to hear you talk positively about the developments for Bond, but I say not for this, as DC would have to go into training before Bond and that is not done in a week AND he has shot back to back for a year now and needs a break. I don't see them startiong to shoot before fall. He will have to ptomote C&A during July, too and do the same for DH in Septemer. Not possible, if he is in the middle of shooting 23 IMO.
But I know what you are saying.
