When she's not sleeping for the sake of art, Tilda Swinton's actually pretty lively.
At the late Roger Ebert's film festival, Ebertfest, on April 20, the actress roused a crowd of 1,500 and led them in a dance-along.
"This is a spiritual service," Swinton said as she instructed the audience to stand. And then, as Barry White's "You're the First, the Last, My Everything" played on, the star took to the aisles to keep the crowd dancing.
Ebert's wife, Chaz, introduced Swinton, and then cut loose on the stage. The event wasn't a memorial for Ebert, who passed away April 4, but it was surely a great way to celebrate the life of the venerated film critic.
