His group – including Lukas Haas and Emile Hirsch – took in Beacher's Madhouse, a variety show – think dancing Oompa Loompas, live monkeys, goats, and exotic burlesque dancers – presented by David Arquette, at the Hollywood Roosevelt Hotel.

"His mood seemed typical," says an onlooker. "He talked to the people he knew and otherwise just made his way through the crowd."
