WATCH: Cheyenne Jackson in 'Behind The Candelabra'

Just weeks away from Steven Soderbergh's much-anticipated Liberace biopic, Behind the Candelabra, we get a first glimpse at Cheyenne Jackson as Liberace's protege Billy Leatherwood. "#GlitterAndBeGay," Jackson wrote last night in an Instagramed screen grab of the behind the scenes clip above.

The clip was part of an 11-minute long behind the scene video special (below), in which we also see Jackson as Billy Leatherwood playing piano alongside Liberace (Michael Douglas):

The rest of the video features footage of Douglas and his leading man, Matt Damon (Scott Thorson), a look at the extravagant sets, and a short interview with Debbie Reynolds who plays Liberace's mother Frances in the biopic--Reynolds personally knew both Liberace and his mother.
