A period piece is a play, performance, or film with an historical setting (typically other than the present) that derives part of its attraction from its faithful and thorough recreation of that setting.
This is fun, maybe I'll do this more. I'll take requests. I've joked before that I'd like a son named Hobbes, who I would force to derive all nouns and concepts. For instance:
Hobbes: Daddy, can I have some soup?Benno: Some what?Hobbes: When water meets meat?Benno: Yes, Hobbes. I love you.Hobbes: And I have a desire for your presence whilst in your presence.
