The 1988 comedy “My Stepmother Is an Alien,” starring Kim Basinger and Dan Aykroyd, was filmed in Southern California. Steven Mills, played by Aykroyd, works as a scientist at this building, where he sends radio signals to space. The same building, found in Westlake Village near Thousand Oaks, was featured in the film “Demolition Man.”

LOCATION: 1 Baxter Way, Westlake Village, CA 91362

Celeste, played by Basinger, first arrives on Earth at the beach front property of Ron Mills, played by John Lovitz. The property, which was also featured in the TV series “Beverly Hills, 90210,” can be found in Hermosa Beach.

LOCATION: 3500 The Strand, Hermosa Beach, CA 90254

The Mills house where Steven and Celeste live can be found in Studio City. The same house was featured in such films as “A League of Their Own,” “Candyman” and “Adams Family Values.” It is also located next door to one of the houses used in the film “Catch Me If You Can.”

LOCATION: 4222 Agnes Ave, Studio City, CA 91604

The front of the property has since been lined with tall hedges, obscuring the view from the street.

Celeste, unaware of how to prepare breakfast, sneaks out in the middle of the night to a diner, where she orders everything on the menu. This scene was filmed at the former Johnie’s Broiler in Downey.  The restaurant has a unique history, having appeared in many other films, such as “Heat,” “Short Cuts,” “License To Drive,” “The Game,” “What’s Love Got To Do With It,” “One Hour Photo” and many more.  In 2007, the building was demolished.  However, Bob’s Big Boy purchased the property years later and rebuilt it based on the original blueprints and even some of the same materials.  So what stands now closely resembles what was seen in the film.
