In a recent interview with BBC RADIO Michael Caine gave his interpretation of the ending to Inception.
As he sees it, the end of the movie isn’t just a dream. “[The spinning top] drops at the end, that’s when I come back on,” Caine said. “If I’m there it’s real, because I’m never in the dream. I’m the guy who invented the dream.”
Hmmm...interesting Michael. Unfortunately my mind is already too blown to understand any further
interpretations of this one.
