Netflix recently announced that its people search feature has landed on Xbox 360. The searching method, which is already included in the PS3 Netflix app, includes actors and directors among its search results. It's especially useful if you like having Julia Roberts movie marathons (and really, who doesn't?). People search also works with Kinect, but good luck getting the system to understand "M. Night Shyamalan."
Also, we discovered that "Tommy Wiseau" does not turn up any results using people search. You're tearing him apart, Netflix
