>>159 Don't they just select comedy roles when there haven't been any good musicals? I don't think they're required to select a musical. The only musical performance I can see slipping in is R Gosling for La La Land, which looks all sorts of magical, but I don't know if its release date will make the nomination cut.
Also, would his role in ISTL qualify for a musical? Is it based on musical numbers performed in the film? Minutes singing? I know they've tightened these definitions since The Martian was considered a comedy last year and people were an-gree!
