Casting director and spring?

The UK casting newsletter PCR (Professional Casting Review) today contains the following information: the casting director on the new Doctor Who series is Andy Pryor, whose casting credits include "Long Time Dead," "Beautiful Thing," "Trainspotting TV: The Long Firm," "Cutting It," "Linda Green" and "In a Land of Plenty," among others. The PCR article also mentions that shooting for the series "is anticipated for late spring" meaning that the production is a bit further along than previously believed. OG speculates that, because of this, an announcement of a new Doctor is probably due within the next month or two.
