Movies set in a Mall/Department Store?
There probably are not many movies that only take place in a Mall or Department Store, are there?
So I guess movies prominently featuring them are okay, too.
Here's some to get us started (spanning 100 years):
Harold Lloyd's Safety Last (1923)
Charlie Chaplin's Modern Times (1936) - Mother of all 'overnight lock-in' fantasies
Jerry Lewis' Who's Minding The Store (1963) - Endorsing the 'credit card' lifestyle
Logan's Run (1976) - Used a Dallas Mall as one of the futuristic locations
Dawn Of The Dead (1978) - Monroeville Mall. This established a solid Z-Movie Trope
The Blues Brothers (1980) - Dixie Square Mall. Three memorable minutes of mayhem
Fast Times At Ridgemont High (1982) - Sherman Oaks Galleria. Is this the original Mallrats?
Gremlins (1984) - Filmset
Mannequin (1987) - Wanamakers, PHL. Predates 'Lars and the Real Girl' by two decades
Career Opportunities (1991) - Target Store #378. Pays tribute to 'Modern Times'
Mallrats (1995) - Eden Prairie Center. ("Would you like a chocolate-covered pretzel?")
Despicable Me 2 (2013) - Designed in the SoCal Style
Fear Street Trilogy (2021) - North DeKalb Mall
Wonka (2023) - The consequent evolution of the food court: A Mall for Foodies!
