Since the first commercial screenings, the box office of the film has partly depended on how accurately the creators fit into the conventions of the genre. So, the first reason for the success of the aforementioned directors was that they knew how to do it and have been practicing for a long time. Having worked with comedies and known its conventions intimately, they understand causality and can easily create a scene that will definitely affect the viewer.
Lighting in comedy films is high key; as for the sound, both diegetic and non-diegetic sounds are used in almost the same proportion; and comedies are most often set in public places - those are usually towns and cities with a welcoming atmosphere. Camera shots may differ depending on the type of a comedy: dark humour, slapstick, or wit. But in comedies there is no hierarchy in the shots — all of the characters are of the same social status, no shot is better than any other. Props are also quite simple — they're something that may inflict pain on a character in a comedic sense.
