plays written earlier or literary works originally in another genre. Famous playwrights such as Henrik Ibsen or Anton Chekhov have had their works adapted several times. The plays of early Greek playwrights Sophocles, Euripides, and Aeschylus are still performed. Adaptations of a playwright's work may be honest to the original or creatively interpreted. If the writers' purpose in re-writing the play is to make a film, they will have to prepare a screenplay. Shakespeare's plays, for example, while still regularly performed in the original form, are often adapted and abridged, especially for the cinema. An example of a creative modern adaptation of a play that nonetheless used the original writer's words, is Baz Luhrmann's version of Romeo and Juliet. The amendment of the name to Romeo + Juliet indicates to the audience that the version will be different from the original. Tom Stoppard's play Rosencrantz and Guildenstern Are Dead is a play inspired by Shakespeare's Hamlet that takes two of Shakespeare's most minor characters and creates a new play in which they are the protagonists. Screenwriter Screenwriters write a screenplay – or script – that provides the words for media productions such as films, television series and video games. Screenwriters may start their careers by writing the screenplay speculatively; that is, they write a script with no advance payment, solicitation or contract. On the other hand, they may be employed or commissioned to adapt the work of a playwright or novelist or other writer. Self-employed writers who are paid by contract to write are known as freelancers and screenwriters often work under this type of arrangement. Screenwriters, playwrights and other writers are inspired by the classic themes and often use similar and familiar plot devices to explore them. For example, in Shakespeare's Hamlet is a "play within a play", which the hero uses to demonstrate the king's guilt. Hamlet hives the co-operation of the actors to set up the play as a thing "wherein I'll catch the conscience of the king". Teleplay writer Joe Menosky deploys the same "play within a play" device in an episode of the science fiction television series Star Trek: Voyager. The bronze-age playwright/hero enlists the support of a Star Trek crew member to create a play that will convince the ruler (or "patron" as he is called), of the futility of war.
