sentences:  In 1917 movie theaters could not get enough Charlie Chaplin comedies, and an enterprising producer hired West, who had been doing comic pantomimes on the vaudeville stage, to make imitation-Chaplin subjects to meet the demand.West, wearing the identical "tramp" costume and makeup, copied Chaplin's movements and gestures so accurately that he is often mistaken for the genuine performer.Reportedly, Chaplin himself saw the Billy West company filming on a Hollywood street once, and told West, "You're a damned good imitator."
