Thespian is a fancy word for actor.
Since this word is related to Thespis, the guy who first took the stage in Ancient Greece.
If you enjoy theater, you can say you enjoy thespian pursuits.
I felt so privileged to be involved with a number of theatre and drama groups, Fools Front Theatre, Aberfoyle Park, Axis Theatre Group, Backstares Theatre and Grassroots Theatre to name a few.
Members would feel comfortable with me photographing their full dress rehearsals, including the Sound and lighting technicians, working backstage tech for the show or play.
