This Is the Life (1917)

At his father’s insistence Billy Drake heads to the family’s South American ammunition company as an emissary. Before leaving, however, the movie-struck Billy spots a beautiful woman standing in front of a theater and imagines that she is a film star. To his delight, he finds the woman on board his ship, as well as political agitator Count Von Nuttenburg who has stolen a movie camera, thinking that it is a new brand of machine gun. Von Nuttenburg shows the camera to Billy. Thinking the Count is a director, and the ship a set for a movie melodrama when the boat lands at a port torn by revolution, Billy insists that the guns and soldiers are part of the show. Not until he and the girl are seized by the rebels and threatened with death, does he admit his error. By a clever ruse, he escapes from his captors and with the help of Federal troops defeats the Count and wins the heart of his pretty shipmate.
