In 1999, M. Night Shyamalan became a household name for writing and directing the film "The Sixth Sense." But in a new interview, he revealed that he was actually behind another film that year too: "She's All That."

At first, the director was shy about the revelation.

"I don't know if I want to tell you which movie I ghost-wrote," h e told Movies.com, laughing. "I ghost-wrote the movie, 'She's All That.'"

Shyamalan, whose repertoire includes films such as "Signs" and "After Earth," continued that he's "strangely, creatively monogamous," and focuses on one project at a time (which would mean, presumably, that the Rachel Leigh Cook/Freddie Prinze Jr. rom-com took up a big chunk of his time at one point!).

"I guess in the history of things, when they're considering a movie or offering me a movie, I'm immediately saying yes or no - and if it's a yes, it's a, 'Yes! Right now! Let's go!' It isn't a 'Let's see,' or 'let's horde it.'" he said. "I'd probably be much wiser to do that, so I could have some stuff ready to go for a few years from now or when I felt something was appropriate, but so far my MO, and I don't [know] if it's good or bad, has been to say yes or no. It makes me lean more on my original fare, stuff I'm writing for myself, and that's always really fun and rewarding and scary. You never know."
