Mumbai Musical

Former Disney animator and director Kevin Lima pitched to DreamWorks a Bollywood-styled musical based on The Ramayana, but told through the point of view of its monkeys.

Plot
It would've follow two common monkeys who become unlikely heroes in a last ditch effort to stop an ancient, thought-to-be-mythical demon from conquering the world.

Development
Going through multiple titles, Monkeys of Bollywood,[48] Monkeys on Mumbai,[49] and Bollywood Superstar Monkey, the film was to feature music by Stephen Schwartz and A. R. Rahman, who's also the film's composers, with the script written by David Sussman. The film was originally planned for a release in December 18, 2015,[50] the release dates kept getting pushed back to the point of being put back into DreamWorks Animation films that are in development

Why it cancelled
Lima revealed that DreamWorks quietly cancelled the film. In an interview with Den of Geeks UK, he said,

It came very close. We were just going into production, we were just starting animation. I’d been working on it for two and a half years. All the songs were written. Stephen Schwartz and A.R. Rahman. We were just ready to start. I have to say that it’s one of the great disappointments of my film career not seeing that one move forward. It had nothing to do with the movie, and everything to do with the politics of selling the studio. Seven of us I think lost movies at that moment in time. With the studio having written it off on their taxes, it means the only way to get it back would be to invest that kind of money again. And it’s tens of millions of dollars. I tried. I really tried. Stephen Schwartz and I took it around town, but when the price tag was revealed, everyone gasped. Ultimately, we couldn’t find a buyer.
