“Would I like to be involved? If I told you that, I’d have to shoot you”
Heh, yea that could be taken to mean:
I'm going to be in it, but, I am under strict secrecy orders and not allowed to say a thing
or
Hell no, I don't want to be involved, but, I don't want to trash show, as that would be unprofessional and possibly career damaging
or
How many freakin' times do I need to tell you people I have no interest in revisiting Doctor Who (or for that matter any of my previous roles, I don't liketo repeat my work, and I'm sick of repeating this statement)
or about 100,000 other things
We can hope it's closest to the first one, though
