I won't be able to see it since I'll be studying abroad, but I really wish I could. I love the movie, and I think the uplifting, poetic spirit of it has the potential to translate well onstage. In particular, I think the scene in the end when they stand on the tables could be a really beautiful climactic musical number.
However, I agree with the poster above me. I am not much of a fan of John Doyle as a director, but I'd see it anyway.
