We’re assuming you already know all about “Smart People,” considering we ran a fancy video interview with some of its cast, including Sarah Jessica Parker, Dennis Quaid and Thomas Haden Church. The film — about a series of folks who think they’re smarter than they really are — was a Sundance fave, and now we have a clip of it featuring “Juno” sensation Ellen Page. Watch it below, and then check out “Smart People” when it hits theaters April 11.
