Factual error: The movie is supposed to be in the 15th century. In a scene we see a priest, wearing a Jesuit robe. But the Jesuit order was founded in the 16th century. So it's impossible that a priest wearing a Jesuit robe appears there.
Continuity mistake: Harold Lloyd, driving a horse-drawn trolley, is trying to draw the attention of a police officer walking on the sidewalk. The officer walks past the Gilt Edge Creamery and the steps of an apartment building. After a close-up of Harold, the officer again walks past the creamery and the apartment building.Steven Lee
