Night Shyamalan won't be trusting Sarah Michelle Gellar with a secret any time soon. When both appeared Friday on The Graham Norton Show, the Buffy star, 45, revealed "the most embarrassing story ever" to the acclaimed filmmaker, 52, regarding his Academy Award-nominated 1999 breakout film The Sixth Sense. The anecdote arose when Shyamalan expressed concern that Gellar had shared spoilers of his upcoming film A Knock at the Cabin. However, she assured him: "No, no, not of that movie." M.
