Joel Coen checks in to see what condition Jeff Bridges is in on the set of The Big Lebowski. The trippy dream sequence, soundtracked by Kenny Rogers and dubbed ‘Gutterballs’, is the Coen brothers’ homage to Busby Berkeley’s 1930 song-and-dance special, Whoopee!, and plays like a really, really stoned Inception. Whoopee! was itself inspired by a Broadway musical and Ziegfeld touches abound, although it’s unlikely that The Dude knows this. Hey, the man’s got marmots on his mind.
