Jeff Bridges -- Rolling to Lebowski Fest

Mark it AWESOME, dude -- because the main cast from "The Big Lebowski" is REUNITING in New York this month during the annual Lebowski Fest!!!!

Jeff Bridges, John Goodman, Steve Buscemi and Julianne Moore are all scheduled to appear at the fest on August 16 ... where they are all set for a Q&A session with fans before watching a screening of the flick.

If you haven't been to a Lebowski Fest -- it's kind of like a Trekkie convention ... with way more pot.
