The last we heard from Tilda Swinton, she was sleeping in a box for art. Before that, she was playing house with David Bowie. And now — well, now she’s dancing.

As the Vimeo caption concisely reads, “Tilda Swinton leads 1,500 people in a dance-along to Barry White’s ‘You’re the First, the Last, My Everything’ during Roger Ebert’s Film Festival in the Virginia Theater on April 20, 2013.” Ebert’s wife, Chaz, goads her into it, and Tilda’s more than game, providing a slightly awkward, slightly stilted, mostly joyful tribute to the great man. And in the process, Tilda once again reminds us that she’s one of those special few celebs — along with folks like James Murphy and Jarvis Cocker, both of whom will always be more interesting than well-known — who know fame is only as good as the weird shit it lets you get away with.

By the way, this dance-along went down on 4/20, so maybe you think Tilda had the help of recreational drugs to get her into the spirit? Wrong: Tilda Swinton doesn’t need drugs. Tilda Swinton is drugs.
