The Lunatic at Large is a 1921 British silent comedy film directed by Henry Edwards and starring Edwards, Chrissie White and Lyell Johnstone. An aristocratic matron attempts to arrange a suitable marriage for her daughter. It is based on a novel by J. Storer Clouston.
Only sketchy details of the film's plot appear to survive. Bill (Edwards) and Lily (White) are newly married. Bert works as a tea salesman and is of a naturally cheery disposition. Over time however, worries about the security of his job and income prey on his mind and he frets over not being able to provide for Lily. With his worries heightened by the fear that he is about to go blind, he falls into a deep depression and becomes a shadow of the happy soul he used to be. Lily becomes desperately anxious about him, and one night has a terrible nightmare in which she dreams that he loses first his sight and then his life (either in a fire, or by being robbed and murdered, depending on the source). However things eventually take a turn for the better and the couple welcome their new baby to the family.
