Streep, who is currently starring as Mary-Louise in Big Little Lies season two, will take on the lead role of Tony winner Dee Dee Allen, a self-obsessed Broadway star played by Beth Leavel on-stage, according to Deadline. Ariana Grande has been cast as closeted, popular teen girl Alyssa (Isabelle McCalla on-stage) who is dating fellow teen Emma, the centre of the show's plot. It has yet to be announced who will play the role of Emma, Grande's love interest.
Nicole Kidman will play Broadway actress Angie Dickinson (Angie Schworer on-stage), while James Corden has been cast as Dee Dee's self-obsessed and out-and-proud Broadway star friend Barry Glickman, played by Brooks Ashmanskas on-stage.
Other cast members include Awkwafina, Andrew Rannells as Trent Oliver and Keegan-Michael Key.
The show follows a group of New York Broadway stars as they arrive in the fictional town of Edgewater in Indiana to help Emma go to her high school's prom after she's been banned from taking a girl as her date. It's reported that Murphy will begin directing the film in December, which is set for a 2020 release.
The Prom, an original concept by Jack Viertel, has been a fan favourite this season on Broadway. It received six Tony Award nominations. The Prom features music by Matthew Sklar, lyrics by Chad Beguelin, and a book by Bob Martin. The film adaptation is also being done by the musicals' original creators.
This is also not Murphy's only project in motion with the streaming service. The creator of tv shows Glee and American Horror Story is also currently working on The Politician, a highly anticipated series starring Gwyneth Paltrow. Murphy is also involved in several other projects yet to be announced.
