The bratty boy was played by Dean Riesner, associate director and co-star Charles Reisner's son. In later years, Dean recounted how he did not want to slap Charles Chaplin's face, even though the story called for him to do so. As a result, Chaplin and his elder brother Syd Chaplin continually slapped each other's faces to convince Riesner what fun it was.
This was the last film in which Charles Chaplin co-starred with Edna Purviance. Chaplin would direct and have a cameo in her next film, L'opinion publique (1923) and produce her lost film, A Woman of the Sea (1926), and she would have cameos in his later films Monsieur Verdoux (1947) and Les feux de la rampe (1952), but this was their last major acting work together.
When The Pilgrim (Charles Chaplin) is leading the church service, he leans on the lectern to drink a glass of water, and his left leg goes up and down two times. Modern audiences often miss the humor in this. The joke is that he is so accustomed to drinking in a bar, that when he leans on something to drink, his leg automatically tries to put his foot up on the foot rail that runs around the base of the bar.
Last film Charles Chaplin made for (Associated) First National, which would merge with Warner Bros. in 1929.
The troublesome young boy in the living room climbs on top of a piece of furniture and a sheet of something sticks to his leg. Modern audiences often don't know that the sheet is a piece of flypaper. Houseflies were common in homes and other buildings before the advent of air conditioning because windows were opened to keep the interiors cool. Flypaper was a type of "sticky trap" that would catch houseflies when they landed on it.
