Still from the film "The Hobbit: An Unexpected Journey."

This week Peter Jackson's "The Hobbit: An Unexpected Journey" opens in theatres, marking Hollywood's big return to Middle Earth.

Along with the usual special effects and 3-D, "The Hobbit" features something new: It was shot at 48 frames per second. That's twice the normal frame rate for film, but there's some controversy over whether it makes the film better, or worse.

Rebecca Keegan of the Los Angeles Times joins the show with more on "The Hobbit," and other news from Hollywood.
