El hombre mosca

Stuntman Harvey Parry revealed for the first time in the television documentary, Hollywood (1980), that Harold Lloyd actually climbed a fake building facade that was constructed over another building's rooftop, positioned so the camera angle could capture the street scene below. Harvey Parry also revealed that he doubled for Lloyd in the long shots of him climbing the building in the distance. Up until then, even the Time-Life version of El hombre mosca (1923) that was aired on PBS contained an opening title declaring that Harold Lloyd climbed the building himself and without the use of a stuntman or trick photography. The stuntman chose to suppress this information until Lloyd's death, and yet, he did not want to detract from the danger of Lloyd's actual stunt work. Lloyd performed the majority of the stunts himself on the rigged facade over a small platform, which was built near the rooftop's edge and still had to be raised a great height to get the proper street perspective for the camera. The size of the platform did not offer much of a safety net, and had Lloyd fallen, there was the risk he could have tumbled off the platform.

When The Boy receives his paycheck from the store employee and opens it, his pay stub has the name "Harold Lloyd" on it. While this is the name of the actor, it is not supposed to be the name of the character. The character, as in most of his films, is known only as The Boy. This is the only incident in Harold Lloyd's film career in which he plays a character using his true name. The scene was edited in without Lloyd's knowledge, and he didn't become aware of it until the movie was complete.

In 1990, The Harold Lloyd Trust and Photoplay Productions presented a 73-minute version of this film in association with Thames Television International, with a musical score written by Carl Davis. The addition of modern credits stretched the time to 74 minutes.
