Vanity Fair isn’t done just yet: In addition to (finally) posting their complete cover story on The Force Awakens, they have an interview with Lawrence Kasdan where he talks about the old film, the new film, and hints that Lando Calrissian’s journey isn’t over just yet.
As for TFA, less is more when it comes to running time:
…it’s turning out really great. J.J. directed it so beautifully, and it’s so exhilarating and everything. It’s a big movie. It’s full of wonderful stuff, incident and character stuff and jokes and effects. One of the things that we always refocus on from the get-go was that it not be one of these very long, bloated blockbusters. A lot of very entertaining movies lately are too long. In the last 20 minutes, you think, why isn’t this over? We didn’t want to make a movie like that. I mean, we were really aiming to have it be—when it’s over you’ll say, “I wish there’s more.” Or, “Wait, is it over?” Because how rarely you get that feeling nowadays, and I think we’re headed there. But it means that there will be constant critical looking at it from now to the end, saying, “Do we need this? Do we need that? Is it better if this comes out, even though we love it?” Killing your darlings.
He’s spot on.
