Courtesy of Vintage Los Angeles, one of my favorite online resources, take a drive down Sunset Boulevard around the time that Rita Hayworth filmed Gildaat Columbia Studios. Columbia was located at Sunset and Gower in the 1940s, so this is a stretch of the street that you would indeed share with Rita and other stars. I love to think of them driving to work at the studios when I watch this.
Of course I love their inclusion of a Hitchcockian soundtrack, too.
