Time Out says
The dude will abide at this loyal homage to the cult Jeff Bridges stoner classic. The two-day festival is back, and "achievers" (fans of the film) show up in droves for a The Big Lebowski screening, bowling, trivia and costume contests, and, of course, White Russians. Grab your bowling shoes and viking helmets and celebrate the 20th anniversary of the movie. The Friday night film screening will feature music by the Kyle Gass Band (of Tenacious D fame), and expect actors from the film to make appearances throughout the weekend as well. In the past Bridges himself has even showed up and sang along to songs with fans. Far out!
