I'm a computer engineer, EMT, and firefighter. I have scooped up brain matter from hot asphalt and run into burning buildings (without even getting paid for it). People ask me how I can do this. I dunno. Training and experience I guess. Doesn't bother me.
But the idea of standing on a stage pretending to be someone else fills me with sheer terror. Even worse would be trying out for that job 100 times and getting rejected every time.
I don't know how actors do it. My hat's off to you.
It's all a matter of perspective. My uncle once brought his kids to see a big show I was in, and afterwards said just what you did. I looked at him, genuinely surprised, and said something like "dude, you're a surgeon. If I screw up at work 2,000 people laugh at me, and forget about it five minutes later; if you screw up at work, someone dies. You really think I should be the one feeling nervous?"
You're right about training and experience, though. I screwed up on stage (in loads of tiny ways, not usually perceptible to anyone but me) every time I ever stepped onto one, and in big ways lots and lots of times as well. But, you know, I always knew that I (with my castmates' help) would get out of it. Failure is inevitable, and it doesn't matter. In fact, if you haven't failed somehow, in at least some small way, then you either don't know what you're doing, or you aren't trying hard enough to succeed.
Also, when I was training young actors I always told them that they will never experience such unconditional love as when they first step in front of an audience. Those people have given at least their time and maybe their money to see you - don't you think they want you to succeed? They're rooting for you, none more so.
To bring this back to the larger subject of the thread, I think all of that's also true of every job interview any of us will ever attend, or conference paper we'll ever deliver. It'll never be perfect, and that's just fine.
I once got an emergency call to a theatre where a fight scene mishap left an actress punched out cold. There's less opportunity for harm in entertainment relative to medicine but it does happen sometimes.
You're right, and oh my god: don't get me started on the abysmal safety record of theatres, particularly towards the non-union end of the scale. I never got a fight director credential, but I was competent, and served as fight captain on any number of shows. 1.) Unarmed fights are the most dangerous type of scene, but also the most likely to be treated cavalierly by people who don't know any better. 2.) There are safe ways to do (just about) everything. A company that can't afford to hire a qualified fight director shouldn't stage fight scenes. Period. End of story.
I've literally walked out of shows (as an audience member) where it's been clear that the actors are doing unsafe things, because I didn't want to see happen what you showed up to. Thanks for being there, and I hope that woman was OK.
She was alert when we got there. We took her in as a precaution/for observation. Don't know what happened after that but the loss of consciousness was brief so she was probably fine.
