Well, it was only so much time until this started to happen. According to IMDB there are several taglines that may or may not be used for the film.
A couple of these are (and my favourites)
Forbidden to Remember; Terrified to Forget.
It will be as though I never existed.
When you can't be with the one you love, will you stay with the one who loves you?
You can view more at the IMDB website.
So guys and gals, what would YOU like to see as the tag line?
personally my big all time fave has to be "forbidden to remember; terrified to forget" because, well, im re-reading new moon for the cojjilion time :p and i got to the bit where she says that, and it says so much.
