ET talks to MARK WAHLBERG about his new thriller, 'The Happening,' which he says he hopes "scares the crap out of people."

The first R-rated movie from the master of twists, M. NIGHT SHYAMALAN, promises intense scenes with high drama and surprises when it hits theaters June 13!

Meanwhile, look for Mark to guest star on "Entourage," for which he is one of the Executive Producers. He "just did a cameo on the golf course with JEREMY PIVEN, which was a lot of fun," he says.
