Patricia Arquette won't be the only one seeing dead people in living rooms this fall, thanks to a two-hour, 3-D episode of NBC's Medium, slated to air Nov. 21. The depth-defying feat was the brainchild of series creator Glenn Gordon Caron, who's been thinking outside the box since his '80s tenure at Moonlighting. "I had wanted to do a 3-D episode of Moonlighting," he says, "but at the time the technology didn't exist to make it possible. [But] technology has come a long way." One thing hasn't changed: Folks will still need to put on those kooky paper glasses, to be distributed in an upcoming issue of TV Guide. Hmmm. Now I see funny-looking people.
