We all know that several Hollywood A-listers also dabble in theater. Actors like Hugh Jackman and Daniel Craig have long been cutting their teeth on both screen and stage for years, as have people like Daniel Radcliffe when he starred in a rendition of the controversial play Equis, Ariana Grande started on Broadway when she was only a child, Jon Hamm has stepped on to the stage a few times, as have Neil Patrick Harris, Jason Alexander, Matthew Broderick, and so many more.

But, there are some in Hollywood who also dabble in jobs behind the curtains instead of in front of them. Some musicians and actors also have written stage plays, some of which were huge successes, and others that were total flops, and in some cases, they adapt their films for the stage. You might be surprised to learn that Tom Waits wrote a play with beat legend William S. Burroughs, or that Stephen King and John Mellencamp wrote a play together. You might also not realize this, but the guy who shouts “INCONCEIVABLE!” all the time in The Princess Bride is one of the most accomplished playwrights of the 20th century.

8 Bono And The Edge Were Involved In A Flop Spider-Man Musical

Okay, technically Bono only wrote the music not the dialogue of the play, but this was such a notorious debacle that it has to be included. Bono and U2 guitarist The Edge wrote the music for Spiderman Turn Off The Dark which is a play based on both the 2002 film and the Greek Myth of Arachne. Production was a notorious debacle, the show ultimately flopped, and it cost $75 million to make.

7 Stephen King And Rocker John Mellencamp Wrote A Horror Play Together

King doesn’t just write books, he has dabbled in writing for both the screen and the stage. Ghost Brothers of Darkland County was co-written with Americana rocker John Mellencamp (a close friend of Stephen King's) and it debuted in 2013. Technically this debuted in Atlanta, not Broadway, but we are likely to see Broadway and off-Broadway renditions of the play sometime when another plucky young director decides to take a crack at it.

The Monty Python alum adapted his comedy troupe's classic film Monty Python and The Holy Grail for the stage by adding musical numbers and adding what the censors would not allow them to do in the 1970s. And thus Spamalot was born and has since been running on Broadway for nearly two decades now. Idle's fellow Python, John Cleese, plans to turn another one of their films, Monty Python's Life of Brian, into a play.

4 Steve Martin Is Not Just A Comedian, He Is An Accomplished Playwright

Steve Martin is a man of many talents. He is considered one of the greatest standup comedians of all time, he is an expert musician and phenomenal banjo player, he has hosted SNL almost as much as Tom Hanks, and several of his films are classics, like The Jerk or LA Story. He is also a great writer with several books and plays to his name. His plays include 2014’s Bright Star, 2016’s Meteor Shower, 2002’s The Underpants, and Picasso At The Lapin Agile in 1996.

3 Tom Waits Wrote A Play With The Guy Who Wrote 'Naked Lunch'

As mentioned in the intro, the avant-garde musician also wrote a play with William S. Burroughs, the controversial author of books like Queer, Junkie, and Naked Lunch. Together they wrote The Black Rider for which Waits also wrote the book and music. The pair co-wrote the play with theater director Robert Wilson.

2 Tyler Perry Started His Career In The Theater

Perry is now the man in charge of a billion-dollar empire of entertainment, but he got his start cutting his teeth on Broadway. In fact, many of the films that Perry is now famous for started as plays, and his character Madea was first introduced on stage before Diary of A Mad Black Woman debuted on screen in 2006. Perry’s plays include Diary of A Mad Black Woman, I Can Do Bad All By Myself, and Why Did I Get Married, which were all adapted for film.
