I know what you mean. I try to squeeze little things into my writing, like a pirate ship called the Daily Sparrow (not a Pirates of the Carribean ref, though)
But I suppose it's even harder for you as you've probably got to know the actors as well, so there's an added dimension to them in your head.

I just noticed.....in Chapter 23 (part three I think) when they're all in the lift in the hospital, and it stops abruptly Angel says 'what did I touch?' and someone else says something along the lines of 'nothing, we stopped'. Is that a reference to Jurassic Park? (Dr Grant and Malcolm say the same thing when the power cutting out stops the visitors car outside the Rex pen)

I love the movie references, even the Shakespear and Edgar Allen Poe quotes (if that's what they were). I think everyone enjoys Burt for the crafty one liners and film references. Please don't kill him off too quick! I'm going to love listening to his retorts under interrogation from the Mallers. (If he survived, that is )
