If I can quote Rocky ...

I only know of one movie that was ever sued for being a parody, and that was "Star Whores", sued by Lucasfilm.

LucasFilm lost.

Parody titles and plots have become the norm in the industry and many movie studios, directors and even stars consider it a badge of honor to have their movie parodied in porn. It is often the topic of conversation on late night talk shows, most notably Davie Letterman, Jay Leno, and quote frequently, Conen O'Brien.

In short: I'm not worried.

Rocky :-)
