“You’re dangerous ’cause you’re honest.” -U2, song Who’s Gonna Ride Your Wild Horses?
The best acting isn’t safe. It’s dangerous. Unpredictable. Honest. Vulnerable. Raw. You’re out there on the edge. Not sure what’s gonna happen next.
It should feel like that, anyway. To you and the audience. (Not “out of control” though. There is a huge difference.)
The right teachers and directors create a very safe environment for you to do dangerous work. Seek them out. For those are who you want to work with.
