Address 780 Gower Street, Hollywood.
Marilyn's mother, Gladys Baker worked there as film editor in 1927.
Just beforeChristmas 1936, she belonged to the small orphans who visited the studios. The RKO showed a movie and offered them some gifts (a junk jewelry string of pearls).
In 1949 Marilyn shot there "Love Happy" of the Marx Brothers.
The RKO was for decades, one of the 5 main Hollywood production companies; it stopped to produce in 1953, after Howard Hughes had took the control of the studios. The former places of the RKO were taken later by the Paramount.
