Screen-to-Stage Adaptation

It's usually the case that hit plays get turned into movies. But more and more nowadays, the opposite is happening, with films being translated for the stage. Some say it's a sign of intellectual bankruptcy in theatre. Hollywood has the same problem, but there are a lot more new successful movies in the last two decades than new successful plays. So the stealing ends up being one way.

These are usually musicals even when they weren't in the first place (see All Musicals Are Adaptations); Adaptation Decay usually occurs here. Movie musicals are also frequently adapted for the stage, and these tend to acquire additional songs in the stage version.

This trope can be taken one step further, by going from movie, to stage musical, to Recursive Adaptation movie-of-the-stage-musical.

Film musicals adapted for the stage

 * 42nd Street
 * Calamity Jane
 * Rodgers and Hammerstein's Cinderella was originally produced for CBS television. Interestingly, the first time it was produced on stage seems to have been a definitely non-standard Pantomime adaptation which played London in 1958.
 * Their one written-for-film musical, State Fair, was adapted for Broadway in 1996.
 * Cry-Baby
 * Dirty Dancing
 * Flashdance
 * Footloose
 * Gigi
 * High School Musical (First two films)
 * High Society
 * Mary Poppins
 * Meet Me in St. Louis: a stock version appeared in the 1960s, and a somewhat different version reached Broadway in 1989.
 * Newsies
 * The Producers. Mel Brooks's original movie can be considered a musical, even though all its musical numbers are diegetic; three songs from the original movie were carried over.
 * Scrooge (The 1970 film)
 * Seven Brides for Seven Brothers
 * Singin' in the Rain
 * Thoroughly Modern Millie
 * Top Hat
 * Victor Victoria
 * White Christmas
 * Willy Wonka and The Chocolate Factory (as Roald Dahl's Willy Wonka)
 * The Wizard of Oz (the 1939 movie) has inspired several musicals. One was allowed to use the songs from the movie but not any of the dialogue that wasn't in the original book. The most recent, in 2011, was adapted by Andrew Lloyd Webber and Tim Rice.
 * Xanadu
 * Disney started making big Broadway productions out of its animated movies in the 1990s with Beauty and The Beast, but there was a stage production of Snow White and The Seven Dwarfs in the 1970s. Disney has since put The Lion King, Tarzan, and The Little Mermaid on Broadway, while their 2011 Aladdin adaptation was created with amateur companies in mind and skipped the Great White Way. There's also a whole series of "Kids" and "Junior" adaptations of other canon films, specifically designed for children to perform.

 * The musical version of Carrie shared a scriptwriter with the movie and is still a Broadway byword for unmitigated failure in Screen-To-Stage Adaptationalizing. So Bad It's Good or unredeemably awful? You decide. (Betty Buckley, who played Miss Collins in the movie and Carrie's mom here, still salvaged a song for her album though.)
 * The Color Purple counted among its producers two people who worked on the movie version—Quincy Jones (co-producer) and Oprah Winfrey (she played Sofia).
 * Back to The Future (currently in development with Alan Silvestri writing songs and Robert Zemeckis producing)

Non-musical stage adaptations of movies

 * Clue: The Play
 * Sadly, there is to date no commercially available stage adaptation of the film. A few players have obtained special permission, and any other performance was and would be technically illegal. There is a musical stage version, but it has nothing to do with the film.
 * Night of the Living Dead: The public domain status, and relatively low budget the film had makes it an easy and convincing transfer onto stage.
 * The 39 Steps has been staged in a recent production with four actors.
 * The Pink Panther Strikes Again (Adapted for amateur stagings in The Eighties)
 * Point Break Live! is a tongue-in-cheek retelling that uses an audience member to fill Keanu Reeves's role (dialogue is provided on cue cards).
 * 12 Angry Men: Technically, it was a play before it was a movie. However, it started as a teleplay on CBS' Studio One program.
 * Does it count as an adaptation if the two versions have almost exactly the same script? The movie has an extra, very short, intro scene and that's about it.
