Act drops are a critical part of any theatrical production. These are usually large curtains or backdrops that are used to signal the end of an act or scene. The term "act drops" is commonly used in theater circles, but there are many other synonyms that can be used to refer to them. Some possible alternatives include "scene change curtain", "curtain call", "stage separator", "intermission curtain", and "closing curtain". Each of these terms captures a slightly different aspect of the act drop and can be used interchangeably depending on the context and the speaker's preference.
