National Geographic Channel's SharkFest programming this year includes the premiere of the “Jaws @ 50” documentary. As you might have guessed from the name, the doc marks the 50th anniversary of the “Jaws” movie, exploring both the making of the movie and its cultural impact. “We were on the real ocean, and we were way out of our element for five months. And we all began going off the deep end, literally,” Steven Spielberg, director of “Jaws,” teases in the trailer. “Jaws at 50” premieres on July 10th. Other shark-related programming includes “Sharks Up Close with Bertie Gregory,” “Investigation Shark Attack,” and ”Super Shark Highway” on July 5th, “Sharks of the North” on July 12th, and ”Shark Quest: Hunt for the Apex Predator” on July 13.
