I can’t remember any actors in this movie, but it was about a crazy woman (blonde) who is obsessed with a guy. There was something about some letters between them, I think. It might have been that he made the whole thing up and that she wasn’t really crazy. The movie was colored and I saw it on tv, I am certain that it was a movie, and not a series.
I thought Renee Zellwegger starred in it, but she doesen’t.
I think the first letter of the movie is O, maybe.
I also vaguely remember a bathroom scene?
