Because Warner Bros wanted to be a little bitch to Harvey.
Because Ron Howard has too much power for anyone to try to piss him off.
There have been four studio films entitled "The Fan".
1949, 1981 and 1996.
I have a feeling it was an ego thing - like that ridiculous title for Precious.
since Warner brothers had copyrighted the title it was up to them to decide if Harvey Weinstein could use it. Harvey even went to the movie Board of Directors and they turned him down.
You can't copyright a title.
copyright might be the wrong word but they did something that allowed the title to be theirs exclusively
Hurry, hurry lover come to me.
Tell me about it, OP.
"I have a feeling it was an ego thing - like that ridiculous title for Precious."
Wrong. R2 has it right. Studios always have the option to do what Warners did to Weinstein, but they don't bother as ultimately it wouldn't pass muster legally. But since the film was about to come out, time was on Warners' side and they decided to make trouble.
The PRECIOUS title was a last-minute change from PUSH (the title of the original novel) as there had been another film earlier the same year called PUSH (a sci-fi POS with Chris Evans and Dakota Fanning).
