Every single thing ever written about Inception comes with a big old SPOILER ALERT. But there’s a YouTube video which reveals something so brilliant, so hidden-right-in-plain-sight-and-yet-utterly-invisible, that…well, just watch the clip after the jump!

The inclusion of the Edith Piaf song was already kind of a filmic meta-joke, since Marion Cotillard (who plays Mal) won an Oscar for playing Piaf in La Vie en Rose. The fact that the Evil Foghorn sound (which plays over the very beginning of the movie, and returns frequently) is actually a slowed-down version of the song could mean quite a few things. Most noticeably, since “Non, je ne regrette rien” is the song the Dream Team uses as their wake-up call, and since the lower dream-levels slow down time…well, this certainly adds a new layer to our burning questions about the ending.

What do you think, PopWatchers? Is this Inception‘s version of the Blade Runner Unicorn? And is this the coolest soundtrack recycling since Mark Mothersbaugh played a Royal Tenenbaums track backwards on the Life Aquatic soundtrack? [AV Club]
