When Blanche arrives at Spike Studios, she is greeted by the Dominatrix Twins. Both are played by the same actress - Thais Maya, who had to do multiple takes with slight wardrobe changes. She was inserted later into the same space with the background action.
The Volvo/snow scene was actually shot in Valley Center, CA in August, not Minneapolis in winter. Temperatures reached 95 degrees F, and Michelle Way's cheeks are red not because of the snow, but because she was roasting in a winter jacket, wool cap and mittens. The Volvo used did not run, and was rented for the day for $100.
When Blanche meets Beaver in the lobby, he's transporting a 32 gallon container of oatmeal to be used in a porn scene. It really was oatmeal, and at the end of the shoot, it was accidentally dumped onto the lobby floor. It took the crew 2 hours to clean it up.
There is one cast member who has a star on the Hollywood Walk of Fame. "Shotgun Tom" Kelly - who voices the morning DJ on the radio while Blanche flosses. He's a legendary radio personality in LA.
