SPOILERS

Here are 2 new videos showing the same scene but from different angles, the dialouge is very clear and they are worth a look.




HERE IS THE MOST IMPORTANT DIALOUGE
A Dalek is trying to evacuate people from their houses. However, one family refuses to come out.

MAN: Laura, get back in the house! Simon, get inside! What do you want with us?
DALEK: Daleks do not answer human questions!
MAN: Leave us alone. Go back in the sky where you came from!

[DALEK trundles forward threateningly]

(Not on the video)

DALEK: Maximum extermination!

[There is the shout of "Boom!" which I'm sure in the actual episode will be an awe-inspiring explosion of some sort]
