If you’re a Christopher Nolan fan, you’ve seen Interstellar (or possibly seen it 100 times). But did you know that before Nolan signed on to make the movie, Interstellar was almost a Steven Spielberg picture? It’s true; Spielberg was attached to direct it in 2006. He brought in Nolan’s brother Jonathan to develop the script, and after Spielberg left the project, Jonathan suggested his brother take over the film. That’s just one of the stellar facts featured in the latest episode of You Think You Know Movies!

The majority of the shots of TARS and the robots in the film were not made by computers; they were practical effects. For the scenes involving the farm and its fields of corn, the production planted real corn. At the end of shooting, the production harvested the corn and sold it — defraying some costs with the money the earned. If you were lucky, maybe you got to eat some of that sweet Interstellar corn a few years ago.
