I have. I think it just might be difficult, in its own way. You’re on stage. The world famous actor, or maybe singer is in the spotlight saying or maybe singing his lines and your job at the time is to do nothing.
I think it is called supporting acting. Even if you are an important well known actor, sometimes, someone else must step into the spotlight and it is your turn to step back into the shadows.
Sometimes as I watch shows, especially when they are live and repeated day by day and for that little while, the success of the show desperately relies on you keeping your mouth shut and drawing little or no attention to yourself.
Sometimes, when I watch shows, I like watching the supporting actors, doing their job, doing nothing.
