If you don't know who Jon Turteltaub is, you probably have seen one of his movies or TV shows without knowing it.  As a filmmaker he's directed movies such as "While You Were Sleeping," "Phenomenon" and those popular "National Treasure" flicks.  He's also a prolific TV producer having shepherded cult favorite "Jericho" and more recently "Harper's Island."  Besides his upcoming adventure "The Sorcerer's Apprentice," the best reason to pay attention to Turteltaub is because of how refreshingly honest he is.  To put it mildly, he just can't help but be honest when speaking to the media. 

Turteltaub trekked up to San Francisco's WonderCon earlier this month to promote "Sorcerer's" with stars Nic Cage, Jay Baruchel and Teresa Palmer.  After showing a number of extended clips from the film which had been previewed to HitFix earlier in the week, he stopped by to chat about Apprentice" and the news that a third "National Treasure" was in the works.  It's a blunt assessment of how the entertainment industry uses the media -- and more specifically -- the internet to float ideas and interest on future projects.

For anyone interested in how all aspects of the business work, it's worth spending the time to check the interview out. Moreover, just as every other instance he's spoken to this pundit, Turteltaub is incredibly entertaining as well.

Turteltaub's "The Sorcerer's Apprentice" opens nationwide on July 16.
