(1947, Joan Crawford, Van Heflin, Ramond Massey)

“I'm pretty sure that I once saw a 1950s detective film set in Los Angeles which had shots of the PCC trams used by the Pacific Electric Railway on its routes to Glendale and Burbank. In one scene, a woman boards one of these cars in the downtown subway terminal in Los Angeles, and a detective is told to follow her. In a later shot,she disembarks from the car in the middle of a suburban roadway.” (thanks Alan Sinclair).
Barry Spence comments:“I'm sure Alan is referring to a 1947 black and white Warner Brothers film titled 'Possessed'. It starred Joan Crawford and Van Heflin.”
