German actors love spit

Some things I've noticed about German theater:
-lots of spit
-confetti
-nudity
-someone sitting in the audience on book (which makes sense because most of the actors have to be in multiple shows at once so I don't fault them for that)
-audience interactivity
-did I mention spit?
-music
-combining acting with other art forms
-in general, fun

German theater seems much more at ease than American theater. All of the American theater that I have seen has tried very hard to keep a solid fourth wall, to keep up the illusion that what is happening on stage is really happening. In German theater, there are no pretenses. If an actor messes up, someone is on book. The audience is meant to be part of the experience.
For example, Kill Your Darlings. The main character--I use the term character loosely because the piece seemed to be more performance art than a play--called audience members on stage to slip around in the rain with the cast. There was no pretense that the audience couldn't see what was happening, so why not invite them to join?
The ease that German theater exists in is something I wish could exist in American theater. I feel that it will not exist in mainstream American theater, because as Americans we are obsessed with perfection instead of letting things just be.

Something that can stay in Germany is the spit, though.
