Okay, "Real sci fi" is a pointlessly prejudicial term, but what I mean is science fiction that, at the time of creation, doesn't break any known rules of science, and relies entirely on plot devices that scientists agree might turn out to be true. This kind of SF has gotten rarer and rarer, as science progresses further and further away from the comprehension of most writers. That is the kind of sci fi that it seems Christopher Nolan (and his brother Jonathan) are making with the assistence of Kip Thorne, who was until recently the Feynman Professor of Theoretical Physics at Caltech. Maybe there will be a lot of bad science by the time it goes in one end and out the other of a major studio, but the Nolans probably have the power, and might have the conviction, to keep it plausible.
The film is called Interstellar, IMDb says it will come out in 2014, and describes it:
An exploration of physicist Kip Thorne's theories of gravity fields, wormholes and several hypotheses that Albert Einstein was never able to prove.
So, that's the good news. The awesome news is that Anne Hathaway is apparently going to be in it. This is awesome news because, since the Dark Knight Rises, Les Miserables, and her responses to assholes in interviews[1. I was looking for the one where she talks about how much it sucks that we live in a culture where people sexualize non-consenting participants, but I couldn't find it, and this one's also pretty great.], she has become one of my favorite actors.
So, at some point next year, we (might) get an awesome new sci fi film, from a fantastic director, featuring a great cast[2. Alright, that's a dubious claim. I love Anne Hathaway, but I have fewer warm feelings about Matthew McConaughey. Nothing vitriolic, just not enthusiastic.], and potentially really solid science.
