Understanding director David Lynch's films is never easy. But with his new picture "Inland Empire" the master of mystery and the macabre is more impenetrable than ever, prompting a journalist to jokingly ask after his mental health. In his latest collaboration with actress Laura Dern, Lynch, who receives a Golden Lion lifetime achievement award from the Venice Film Festival later on Wednesday, blurs the boundaries between one story and the next, and between dream and reality. Nearly three hours long, the most obvious plotline centers around the making of a movie and how the lead actress fears the wrath of her husband when she has an affair with her co-star.
