Ren-Mar Studios was a rental studio located at 846 N. Cahuenga Blvd. in Hollywood, California, on premises that were formerly the home of Desilu Productions. It was first built in 1915 as Metro Pictures Back Lot #3, and has been used for a wide variety of film and television production, and the studio has been known by many different names. In 1953, after filming the first two seasons of TV's I Love Lucy at another studio, Lucille Ball and Desi Arnaz were looking for a larger studio. They looked at the lot (known at the time as Motion Picture Center) and signed a ten-year lease on the property. It then became Desilu Studios. About 1956, after Desilu bought and/or leased other studios in Hollywood and Culver City, it was changed to Desilu-Cahuenga Studios to avoid confusion with the other Desilu Studios. Since 1974, Ren-Mar has been an independently owned and operated studio, available for use by producers.
I Love Lucy (seasons 3-6, 1953–1957), The Lucy-Desi Comedy Hour (1957–1960), The Dick Van Dyke Show (1961–1966), Make Room for Daddy, Hogan's Heroes, The Andy Griffith Show, The Jack Benny Show, That Girl, Seinfeld, The Golden Girls, NewsRadio, Ally McBeal, and Lizzie McGuire are among the television series that have been filmed entirely or partially at Ren-Mar. In addition, music videos are often filmed at the studio, including those of Madonna, INXS, Michael Jackson, and Britney Spears. The front (Cahuenga Boulevard) gate of Ren-Mar was used to represent the "Maroon Cartoon Studio" for the 1988 film Who Framed Roger Rabbit. In 1991, the Richard Simmons exercise tape, "Sweatin' to the Oldies 3" was taped at Ren-Mar. NBC 80's fave "Empty Nest" starring Richard Mulligan was also taped here.
The latest shows produced at Ren-Mar were FNMTV, Monk, and Weeds.
In January 2010, Ren-Mar Studios was bought by Red Digital Cinema Camera Company. The complex was renamed "Red Studios – Hollywood".
