She and her team went to great lengths to avoid spoilers for the finale, an effort which seems to have paid off, since nothing major from the two episodes has leaked. Talalay says of the different things they've done:
“We put out script sides that were incorrect. We published for the crew a script that was incorrect. The actors when they finally did the correct lines mouthed them. We were outside St Paul’s Cathedral with everyone on their iPhone recording. I’m still shocked that the big spoilers, the secrets, have been kept until now. People were taking cameras and sticking them in the tent. Taking pictures of the sound man’s script! So I give huge credit to the team for figuring out a process! I so enjoy all the theories as to who is Missy and what’s going on!”The second episode of the two-part finale, "Death in Heaven," airs this Saturday, 8 November at 8pm on BBC One and 9/8 CST on BBC America.
