T.R. Knight and Patrick Stewart came out to support their Broadway play, A Life in the Theatre.
The show is a revival of a 1977 David Mamet play, where T.R. stars as a new actor on the scene and Patrick acts as his mentor. Trouble ensues when the student outshines the master.
Life begins previews next month and runs through January.
Go get 'em, honey!
