The party sprawled through the outdoor garden terrace of the Chateau Marmont—once home to icons Jim Morrison, Howard Hughes and Greta Garbo—and into its moody, dimly-lit lounge, Oscar nominees, A-listers and industry elite mingling, perched above West Hollywood’s sunset strip. The bash Thursday evening kicked off the Oscar weekend, and marked the fifth such soiree held in the Chateau by official Academy sponsor Cadillac. Cadillac takes over Chateau Marmont for their annual Oscar Week celebration.
