Just like scores of real world colleges and universities across the country, Lost University is now back in session.

The fictional university meant to teach Lost fans on the "fringe" science and other elements of J.J. Abrams' show can begin classes anew as the series approaches its final season.

It's no joke and no mere marketing gimmick as the "university" brings in legitimate scientists, psychologists, language experts and other experts to discuss the themes and science of Lost.

The current course catalog includes: PHI 201: I'M RIGHT, YOU'RE WRONG: THE US VS. THEM MENTALITY -- "This course examines the complex relationship between Right vs. Wrong, Us vs. Them, and Good vs. Evil, and applies it to both Lost and the real world."

Plenty of freshman (and drunken upperclassmen at most state colleges) get lost on university campuses every day. But, the developers of the new Lost: Season Five Blu-Ray set want you to lose yourself in its "school" willingly.

Opening for "classes" December 8, Lost University is a special feature of the Blu-ray offering a "captivating new immersive bonus experience powered by BD-Live technology. A series of interactive "lectures" expands "the world of Lost, giving viewers around the world an unprecedented interactive experience unlike any other before it."

Walt Disney Studios Home Entertainment arranged a strong collection of "professors" to teach the university seminars. Cast members include Naveen Andrews, Jorge Garcia, Josh Holloway, Daniel Dae Kim, Yunjin Kim, Evangeline Lilly, Terry O'Quinn, Michael Emerson and Henry Ian Cusik.
