Die, Mommie, Die!

Die, Mommie, Die is a 2003 American satirical comedy film written by Charles Busch, who also plays the lead role. Partly spoof and partly homage, it draws heavily on the tropes and themes of American Grande Dame Guignol films and plays from the 1950s and 1960s that featured strong, sometimes dominating female leads, such as those by Bette Davis Dead Ringer and Ethel Merman Gypsy. It was later performed onstage in 2007 under the same name.
