"Hamlet calls this new play "The Mouse-trap" (a title that Agatha Christie later took for the long-running play "The Mousetrap").The play "I Hate Hamlet" and the movie "A Midwinter's Tale" are about a production of "Hamlet", which in turn includes a production of "The Murder of Gonzago", as does the Hamlet-based film "Rosencrantz & Guildenstern Are Dead" which even features a third-level puppet theatre version within their play.
