Quinto would play the composer and pianist, who, with brother Ira, was responsible for more than a dozen Broadway shows before dying at age 38.
DreamWorks is supplying accent and dialogue coaches for Quinto, Deadline says.
Doug Wright wrote the script, and Marc Platt and singer/pianist Michael Feinstein are producing. A DreamWorks insider told Deadline that this is one of three projects Spielberg is looking at for his next film.
