A snippet from the Wikipedia entry on Donnie Darko:

In the film, Donnie refers to “Married with Children” (1987) and, more specifically, Christina Applegate during conversations about sex with his therapist. The script initially called for Donnie’s fantasies to be about Alyssa Milano. This had to be changed however when Kelly was denied the legal rights to reference her in this manner.

Does it strike anyone else as just a wee bit ridiculous that we live in a society where the right to have a fictional character refer to an actress who portrayed another fictional television character can be denied at all?
