Christopher Nolan's known for keeping a tight lid over set photos and the like getting out from his films. However, The Dark Knight Rises saw a huge amount of photos leak out onto the Internet and it looks like Interstellar may be the same.

The film, which isn't due out until 2015, has begun filming and already, set photos are emerging on the Internet. We've no idea what's going on from the photos we can see, we're guessing it's some sort of dust-storm or something. We can see Matthew McConaughey, Topher Grace, John Lithgow and Jessica Chastain in action, but not much else.

Some more plot details have leaked as well, which gives us a better idea of what the film will actually be about. According to JoBlo and a local newspaper near where the production is based, the plot involves scientists travelling through black holes to find - wait for it - new crops as the world is teetering on apocalypse after corn is the last crop left to be cultivated. Yeah, sounds wacky.

Look at it like this - if somebody explained the plot of Inception to you before you'd seen the film, you'd have laughed and said it was stupid as all hell. And Inception was, well, Inception.

Anyways, check out these set photos!
