On The Verge (play) - Grover Et Al.

Grover Et Al.

The fact that one actor plays eight different characters is probably the "gimmick" of the show, an extra detail added by the author to make circumstances more interesting (There is a fifteen second costume change at one point in the show). Almost no background is given for any of these characters, so the actor is able to take considerable artistic license with them. The nature of the characters themselves allow for more than enough over-the-top acting.
