Indie- darling Richard Linklater's seminal masterpiece film 'Boyhood' was shot for a little more than a decade. And with this next project, Linklater would be pushing the envelope further than before. He is said to base his next film on Stephen Sondheim's musical 'Merrily We Roll Around'.

'Pitch Perfect' star Ben Platt and 'Booksmart' actor Beanie Feldstein, both having roots in Broadway, have been cast as the main leads for this ambitious project. The movie will follow Franklin Shepard, a talented Broadway composer who abandons his theater career in New York and all his friends to produce movies in Los Angeles.

Like the play, the musical begins at the height of his Hollywood fame and moves backward in time, showing snapshots of the most important moments in Frank's life that shaped the man he is today. Platt will play the lead, while Feldstein will play his best friend, theater critic Mary Flynn.

Currently, Richard Linklater is working on the pre-production of his Houston based space film and a John Brinkley biopic starring Robert Downey Jr. His movie 'Where'd You Go Bernadette' starring Cate Blanchet is currently in theatres.
