When I was unable to find an image in an article, which was often the case, I simply had to rely on my knowledge of Douglas, which I supplemented with biographies written by those who know far more than I; Dr. Tracey Goessel's The First King of Hollywood was my trusty go-to, especially when it came to determining dates. For instance, I knew the image above of Douglas with a crate had to be from 1920 or 1921. It was before production began on The Three Musketeers, as he wasn't donning a moustache. The message on the crate was my second clue. I found that “California Ripe Olive Day” was first celebrated on February 21, 1921. I also considered Douglas' bandaged hand. I knew Dr. Goessel's book touched upon some of the injuries he sustained while performing his stunts, and she found that as he was leaping through a window for a scene in The Nut (1921), “he caught his foot on the sill and crashed six feet onto the pavement” fracturing his left hand. Dr. Goessel even mentioned the names of some of Douglas’ dogs, including his Alaskan Malamutes, Ginger and Rex. Her information combined with a 1917 article from The Photo-Play Journal helped me cross another image off my list.
Two negatives of Douglas and Charlie Chaplin posing with a young woman were of particular interest to those who had worked on the collection in the past. These candid shots looked as though they had been taken around 1917, but I couldn’t place their guest. Was she a friend, a relative, or a visitor to the studio? Was she associated more with Chaplin than Douglas? I knew the best way to find out would be to enlist Charlie’s dedicated fan base, so I wrote to Jessica Buxton, a knowledgeable researcher and enthusiast who maintains the blog, Discovering Chaplin. Jessica thought I was correct about the date considering Charlie’s hair was still naturally dark, but she wasn’t sure about the lady in question. She suggested we ask her equally devoted friend, Dominique Dugros. Jessica and Dominique graciously dedicated their time to help me search, and they soon determined that our mystery maiden might have been the stage actress Marie Doro. Chaplin had been quite taken with Doro when they worked together in the London revival of Sherlock Holmes in 1905. According to a Motion Picture News article from 1916, which was around the time Marie started making pictures for the Lasky Company, she held a reception in Hollywood in which Charlie and Douglas were guests. I haven’t been able to find this exact candid in any publications, so, of course I will continue to attempt to confirm the possibility, but there is a noticeable resemblance. Perhaps our mystery has been solved! Either way, I have made two wonderful new acquaintances along the way.
