And Starring Pancho Villa as HimselfGoofs
Griffith is shown to be making a short western in New York in 1914. It is a very cloudy and overcast day. In reality, Griffith has already moved his stock company out to California by then, plus he would have known not to shoot on such a cloudy day (there would not be enough light for the exposure). He also did not film any westerns in 1914, and would have been at work on The Battle of the Sexes (1914) at this time.
At the beginning of the film, Pancho Villa makes a remark about Charlie Chaplin. This scene takes place sometime between the end of 1913 and the beginning of 1914. Chaplin made his screen debut in January 1914. In any case, there's no chance that Pancho Villa would have known Chaplin's films, considering that at that time (1914) the future star was just only another Keystone employee.
