There are a great deal of Broadway musicals and adaptations that have been inspired by the small screen. While the industry does often draw inspiration from books and films, it's not completely out of the box to see a Broadway production based on a TV show.
There's a number of series that would really lend themselves to the format. Whether it's because they are an easy production to add musical elements to, or perhaps because their staging and story would be perfect to see live, there's a nugget of inspiration in each series that could certainly help to great the next big show!
Glee
Glee seems like a natural fit for a Broadway adaptation. The production of the show itself certainly feels like it belongs on stage, with both a number of original songs to bring along with them and some brilliant covers that have come to define these characters.
A school setting is another very easy thing to adapt to the stage and a show could very easily track their first year as they try to win nationals, only to fall short. It's an inspirational tale and one that would certainly spark nostalgia in fans.
Community
The study room in Community often hosted some brilliant bottle episodes. It may also be the perfect place to set a large part of a Broadway production in. The school has had some wacky stories over the years.
With the production able to draw upon the fact that the show has had musical elements, alongside tropes of the show such as the paintball wars, there's a lot of great elements to bring together to complete the 6 seasons and a movie (or in this case a theater production) mantra.
Stranger Things
Stranger Things may have some terrifying creatures that could prove difficult to bring to life on stage, but it also has magical elements that are sure to impress audiences. The nostalgic element of the show is also perfect for the stage.
With an '80s vibe and a thrilling new adventure for the kids of Hawkins to go on, there are a great number of directions a Broadway production of the show could go in, all of them are just as equally exciting. In many ways, this could go in the direction of other productions like The Cursed Child.
GLOW
Glow may have just been canceled by Netflix but that doesn't mean the story can't continue. It would be quite easy to stage a show like this, as it could all take place around a single night or wrestling. The stage setup would therefore need a ring and a backstage area.
It could continue to explore these characters in a smaller setting, while also giving fans of the show some of the action they have come to expect. It would be an inventive way to continue the story, but one that does it justice. Plus it would feel a little like the season 2 Las Vegas production they put on.
Downton Abbey
Downton Abbey is a British period piece that feels right at home on stage. The series is relatively long, but it would make sense to take a chapter from this story that has never been seen on screen before and adapt it to Broadway.
Much like the film version of the show did, this could therefore continue on some of the stories developed out. Period dramas like this have always had their time on stage, since it's a glamorous production with a number of dramatic elements that allow this to feel almost like an indie production.
Good Omens
Good Omens was a fantastic fantasy book created by Neil Gaiman and Terry Pratchett. It saw the anti-Christ be brought into the world and the apocalypse seemingly start to begin. But the book and subsequent show also saw the development of the relationship between an angel and a demon.
The series and the book itself could easily be adapted into a smaller show, focusing on some of the key elements of the drama. The fantasy elements would work well on stage and there's a key relationship to focus around. It could really be a lot of fun to watch.
Friends
Friends may be one of the most influential sit-coms of all time and it's a shock that there haven't been serious plans to bring it to stage. Having the stage set up with the two apartments and Central Perks would be an easy way to present it. It may even be pitched as a celebration of the show.
Plus, it would be fascinating to see who the show would cast as the 6 leads of the production. It would be funny, entertaining and hopefully, call back to some of the classic moments in the series. Other classic comedies such as Only Fools And Horses have been successfully adapted to the stage as if it is another story set within that universe; Friends could do the same.
The Good Place
The Good Place was perhaps one of the most surprisingly charming shows of the 21st century. Incredibly deep, well written and endlessly funny, it may be difficult to replicate exactly what was brought to screen on to the stage.
However, there are a great many details from the series that could be brought to Broadway, with the first season acting as the best way to adapt this massive success to the stage. The many tricks of the Good Place and Bad place would really play well live and it would be fun to see these relationships develop again.
Watchmen
The DC property may be an odd choice to bring on to the stage, considering the level of crazy effects involved with the show, but there's perhaps a way to adapt this series, or even the comic it is based on.
Watchmen is partially about the politics of super-heroics and the way in which the comic genre can be twisted. These ideas could be put on stage, in a different format, with a few of the powers achieved through production magic. If there's no season 2, this may be the next best option.
Star Trek
The Star Trek franchise is currently trying a lot of different concepts, in order to tell the best stories within that universe. From big blockbuster films to new TV shows (and an animated series that looks at the lower decks of these ships).
The next step naturally feels like Broadway. It would be a huge departure but one that could see the Star Trek franchise moved to the stage, with the upper decks serving as the area of most of the action. Amazing costumes, effects, and prosthetics would really bring this together, plus some dimension-hopping could give the show a fun, meta-musical twist.
