Inception: Christopher Nolan's decade-old mindbender

Hilarious Entertainmentx on Instagram: "Christopher Nolan’s mind-bending film Inception was inspired by his own dreams — and he actually made a short film as a test for the complex dream concept before making the full movie! Also, the iconic “kick” sound that signals waking up from a dream? That deep booming noise is actually a slowed-down Édith Piaf song called Non, Je Ne Regrette Rien. Nolan used it to connect different dream layers in the story."
