I'm of two minds. There's a movie version of basically this same behind-the-scenes story also in development, with Oscar Isaac as Coppola, also starring Jake Gyllenhaal and Elle Fanning, and the script is INCREDIBLE. It comes at it from a slightly different angle, with Coppola as the main character, and I cannot emphasize enough how fun/good it is, with dialogue that absolutely sings. So, while this does indeed look good, I can only see it in comparison to the other version, which I think would have been so much better, but I'm worried might not get made now because of this version.
I posted about it here a while back...
