Zachary Quinto, from Spock to Gershwin

That's the word - that Zachary Quinto, known for his a funny face in Star Trek, will play George Gershwin in an upcoming Steven Spielberg film about the composer.

Now this opens up all kinds of casting questions. Will Chris Pine play Ira Gershwin? I can see Winona Ryder in the role of Kitty Carlisle Hart. Or maybe as Kay Swift.
