consider all of the comedy with a military situation that have be do in history and someone have to be the first . one could make a case that in shoulder arm and charlie chaplin invent the genre . hard to believe that back then this be a daring move . when you consider that some of the best film involve such people a bob hope and abbott and costello and laurel and hardy involve military service and make during war time and it just something you accept and laugh at . in the first world war chaplin along with fellow star douglas fairbanks and mary pickford go out on bond tour . he be a great supporter of the allied cause and unusual for someone of his left wing view . it would seem only natural that the tramp would be draft and unfortunately would flummox around and wreak havoc on all . a lot of thing you would see in the service comedy of world war ii get their start in shoulder arm . chaplin have no more imitator because within a few week of the film release and the war be over . but a comedy art form have be establish by one of comedy great genius .
