Christopher Nolan’s Inception ultimately became one of the most celebrated sci-fi thrillers of the last decade, but did you know Nolan originally envisioned his unique heist story as a horror film? That’s just one of the facts packed into the latest episode of You Think You Know Movies, which burrows deep into your subconscious for a journey into Inception!

Although the film ultimately (and awesomely) starred Leonardo DiCaprio as the enigmatic dream thief Cobb, the role was originally offered to Will Smith. Interestingly, Cobb is also the name of the main character in Christopher Nolan’s directorial debut, Following. That character’s profession? A thief, just like the Cobb in Inception (minus the dream-infiltration technology, of course). Insert your own crazy fan theories here.
