Power to the people who punish bad cinema!

At the Baltimore premier of her latest film, Some Kind of Happiness, Honey Whitlock (Melanie Griffith) is kidnapped by celluloid terrorist Cecil B. Demented (Stephen Dorff) and his gang of truly independent film makers. They start filming Demented's film, all of it one take, and almost all of it involving the general public (taken hostage, to ensure realistic behaviour).

As you might have guessed (who else would film in a dump (Whitlock's word, not mine!) like Baltimore?), it's a John Waters film.
