In the course of just the first few films with Chaplin, easily the biggest film star in the world, Eric Campbell himself became famous. Recall the scene where The Tramp literally gaslights Campbell in Easy Street? It's still one of the funniest and most memorable sequences in screen history. His thick, animalistic eyebrows, and patented slow burn, soon inspired imitators of himself (Oliver Hardy was one of them), just as Chaplin inspired imitators- one of them ironically being Stan Laurel, who knew Campbell and Chaplin from their days with Karno. So, flush with cash, Campbell brought his wife and daughter to Hollywood. Then, in an all too Hollywood fashion, disaster struck. Campbell's wife died suddenly, his daughter was in an accident, Campbell remarried a golddigger a month after his first wife's death, then divorced her two months later, and then himself died in an early morning drunken driving accident, in December of 1917. Chaplin never again had such a great onscreen foe and partner, and never again was The Tramp so delightfully wicked, which led to the detractors of Chaplin's success and greatness arming themselves with his perceived flaws, and conveniently ignoring the brilliance of his anarchic Essanay and Mutual days.
The documentary does dig up many outtakes from Chaplin films, and the onscreen and offscreen chemistry between the two men is palpable. There are many archival documents, from Campbell's childhood in Dunoon, Scotland (although his exact date of birth is unknown- anywhere from 1878-1885, and his full name was Alfred Eric Campbell) to Campbell's second wife's hilarious petition for divorce, claiming cruelty that includes exposure to hula dancing. There are the requisite experts, such as Campbell's daughter, and Chaplin expert David Robinson. But, the best thing about the film is nothing within the film, but simply that it exists.
The best thing about the prevalence of DVDs is that they provide an affordable way to preserve the history of the dominant art form of the Twentieth Century, and its oft-forgotten contributors- major and minor.
