Who knew only 3 1/2 minutes could generate so much excitement?  The always secretive Christopher Nolan did, that’s who.  The “Dark Knight” mastermind showed a clip from his new Leonardo DiCaprio thriller “Inception” at San Francisco’s WonderCon this past weekend and people were still talking about it the following day.

Not much is still known about Nolan’s latest endeavor, except that it appears to deal with covert espionage within character’s dreams.  Could it be “The Matrix Revolutions” without the leather jackets?  If you take that as a compliment to the Wachowskis , then yes.  Moreover, the visually impressive film is slowly positioning itself  for a potential awards season run later this year.  There’s still a long way to go until the film debuts on July 16, but this weekend’s reveal was more than enough to push “Inception” to the top spot in the power rankings.
