No. Apparently, hubby Neil was laid up sick (I think I read somewhere that 
he had appendicitis, but I could be wrong), so she stayed at home.

As far as I'm concerned, it's just a nervous tick - the reason for 
including it several times is that not only does David Tenant do it, but so 
does Brendan Gleeson: it's a cinematic hint that a correspondence should be 
drawn between the two characters.

He was younger when he was incarcerated? :-)

That would have made him look more like a stereotypical movie vampire, 
which whilst an appropriate image per se, would have been a little 
misleading if you ask me. Personally, I was hoping for more serpentine eyes 
(as I think I've already mentioned). I also suspect that fangs would make 
talking a little difficult (although long teeth would tend to accentuate 
sibilants, which would be more than appropriate...).
