Jeff Bridges and his aptly named band the Abiders will be the headlining act at this year's Lebowski Fest in Los Angeles on April 25.

The festival, which takes place once a year, gives fans of the Coen brothers' 1998 classic movie 'The Big Lebowski' a chance to gather and nerd out over their favorite characters and quotes.

On the first day of the two-day festival, Bridges and his band will go on right before a screening of the film. This will be followed by bowling, a costume party and Dude-based trivia. Kyle Gass, one-half of the rock duo Tenacious D, will be opening the first day of the festival with the Kyle Gass Band.

The event's website also makes vague mention of "other special guests from the film," whatever that means. We're guessing it means that they're hoping the Duder's presence will convince some of the other stars from the film to show up, though it could mean anything, really.

No mention was made of how much dairy will be consumed with all the White Russians people will be chugging or did the website suggest any non-dairy alternatives for the lactose-intolerant fans.
