The three previous 'Nu-Who' first Doctor episodes have been between 45 minutes and 65 minutes, so the casual 'new Doctor' audience being risked on a feature-length episode with 'slower moments' is unchartered territory IMO.”
Well, we'll see - but I do think that a longer running time is a bonus, not a detriment, as is the later starting time (assuming that it airs at 7.35, the same time as the cinema screenings). On August Saturdays the peak overall TV audience is likely to be around 8.30 to 9 pm, so the longer and later DW runs the better it is likely to rate.
And, again from the cinema screenings, it does not look as though the episode will be a full hour and a half. It seems to be between 75 and 80 minutes in length, not 90.
