Just thinking about this (changed my username in fact to a character), what films are the ones that if you are flicking through channels and come upon, you just have to watch to the end even though you have seen them over and over again!
Mine are:
First Wives Club
Stepmom
The Island
The Trueman Show
I can guarantee if any of those films are on, I will change the channel and watch until done :)
What’s yours?
