One Act Plays
A One Act Play, or more commonly "one act", is a short play that takes place in one act or scene, as opposed to plays that take place over a number of scenes in one or more acts. They tend to be simpler and have fewer props, scenery and cast members (sometimes only one). Such plays are often showcased in a series. Unlike other plays which usually are published one play per book, one acts are usually published in anthologies or collections.
