Kushner prefers that the theatricality be transparent. In the "Playwright's Notes" he writes: "The play benefits from a pared-down style of presentation, with minimal scenery and scene shifts done rapidly (no blackouts!), employing the cast as well as stagehands — which makes for an actor-driven event, as this must be. The moments of magic [...] are to be fully realized, as bits of wonderful theatrical illusion — which means it's OK if the wires show, and maybe it's good that they do..." Kushner is an admirer of Brecht, who practiced a style of theatrical production whereby audiences were often reminded that they were in a theatre. The choice to have "no blackouts" allows audiences to participate in the construction of a malleable theatrical world.
One of the many theatrical devices in Angels is that each of the eight main actors has one or several other minor roles in the play. For example, the actor playing the nurse, Emily, also plays the Angel, Sister Ella Chapter (a real estate agent), and a homeless woman. This doubling and tripling of roles encourages the audience to consider the elasticity of, for example, gender and sexual identities.
