At least that's the report coming in from TMZ:

John Hughes has died of a heart attack.

Hughes suffered the heart attack while taking a morning walk during a trip to NYC to visit family.

He directed such '80s hit films as "The Breakfast Club," Weird Science," "Sixteen Candles" and "Ferris Bueller's Day Off."

More info when we know it.

UPDATE: CNN confirms it. So does the NYT.
