Even easier than The Film of the Book. The dialogue is already written, so you do not need a scriptwiter. If you are lucky enough, the actors who played it on stage will accept to play it on screen, so you do not need a casting and the actors will know their text better than any film director could imagine.
Yet, there are some drawbacks: in theatre plays, the dialogue is essential, too essential for a movie which will often seem too verbose. Theatre play adaptations also tend to be very static, because, in a play, the action happens in a very limited number of places (for obvious reasons). Consequently, these films are more likely to be a Bottle Episode or make use of Minimalism, Minimalist Cast and The Oner than other movies because of the technical limitations of stage plays.
Running time is the most frequent difference between a play and its movie. While not a hard limit, it is rare to see a film over 3 hours. Many plays exceed this (unabridged Hamlet can run for over 4 hours) and their film adaptations are usually cut to fit into this length. Even if the play clocks in at 3 hours or so cuts may be made to make room for establishing shots if the elimination of transitions doesn't create enough time.
Unlike books and other media adaptations, Plays often get made into films multiple times. This is perhaps due to their nature as blueprints for storytelling rather than realized works on their own.
In order to get around the common drawbacks of adaptations of theatre plays (verbosity, lack of action...), there is another approach. These adaptations will use the plot of a theatre play, but will change the setting and completely rewrite the dialogue. The works of William Shakespeare are a frequent target of this kind of adaptation. Alternatively, an adaptation may retain the plot and general setting, but expand the action, with events described in dialogue in the play due to the limitations of what can be seen on stage directly depicted in the film.
Popular stage musicals are also frequently adapted into films. Almost all movie musicals made after the studio era are examples of this.
Sister Trope of The Film of the Book (adaptations of a book into a film), The Film of the Series and The Movie (adaptations of a TV series into a film). Inversion of Screen-to-Stage Adaptation. Might overlap with The Bard on Board (loose adaptations of William Shakespeare's works to any kind of media).
In the lists below "Production" means a the play was performed without significant change to its dialog (usually just abridgement), an "Adaptation" means the play's basic plot is present, but the dialog has been replaced.
Film Productions of William Shakespeare's plays:As befits his position as one of the most important authors of the English language and arguably the world, Shakespeare's plays were among the first to find their way to film, with some being adapted for silent film. There's a lot of Kenneth Branagh productions listed here as he seems intent on committing all of Shakespeare's plays to film. Unless otherwise noted, productions are named after their directors in the list below:
- 1948: Lawrence Oliver
- 1964: Grigori Kozintsev
- 1969: Tony Richardson
- 1990: Franco Zeffirelli's production stars Mel Gibson and had a realistic medieval setting.
- 1996: Kenneth Branagh's take is notable for being unabridged, something that's rare even on the stage itself, leading to a four-hour-long rendition. It is also notable for its Edwardian Setting Update, particularly the costumes for which it received an Oscar. It received an amusing Take That! in Blackadder Back and Forth:
Blackadder: [kicking Shakespeare in the shin] And that is for Ken Branagh's endless uncut four-hour version of Hamlet!
Shakespeare: Who's Ken Branagh?
Blackadder: I'll tell him you said that. And I think he'll be very hurt.
- 2000: Michael Almereyda's 2000 retelling uses the conceit of a "Denmark Inc." and sets the play in the current day.
- Henry V

- 1968: Franco Zeffirelli
- 1996: Baz Luhrmann famous for being set in modern times and made to appeal to the MTV generation.
- The Taming of the Shrew:
- 1929: The first talkie film adaptation of a Shakespeare play, directed by Sam Taylor and starring real-life couple Douglas Fairbanks and Mary Pickford. Notable for heavily reslanting the play to suggest that Katherine is not really "tamed" at all. Also notorious for the much-mocked writing credit "Based on William Shakespeare's comedy... with additional dialogue by Sam Taylor".
- Titus Andronicus
- 1999: Julie Taymor
