Sir Michael Caine reveals real end of 'Inception'

Spoiler alert! Don't want to know the official ending of "Inception"?  Stop reading now. Sir Michael Caine revealed if the spinning top drops or keeps turning in an interview with BBC radio (via Gizmodo):  "[The spinning top] drops at the end, that's when I come back on. If I'm there it's real, because I'm never in the dream. I'm the guy who invented the dream." So that means… Leonardo DiCaprio's reunion with his children was real life, not a dream within a dream within a dream.
