ESPN has released a preview of their latest E:60 documentary, WWE: Behind the Curtain. This documentary takes viewers through the inner workings of the WWE Performance Center training facilities in Florida (you know, NXT’s home turf), and it includes interviews with WWE Hall of Famer ‘Stone Cold’ Steve Austin, WWE icon Dwayne ‘The Rock’ Johnson, and WWE Owner/Chairman Vince McMahon.  It’s unknown at this time whether or not they’ll address the controversy surrounding Bill DeMott and the allegations regarding the horrible, subhuman training conditions he cultivated, but due to the fact that this doc is airing in the first place, I’d doubt it’ll be addressed past a post-show, pre-end credit text update screen. ‘E:60′ Pictures presents ‘WWE: Behind the Curtain’ is currently scheduled to air on May 5 on ESPN.
