Oh one other thing...
The meaning and origin of MOS
The popular explanation of MOS to indicate a take without sound is that MOS (spoken as "M.O.S." not "moss") is an acronym for "Mit Out Sprechen" (without speaking) or "Mit Out Sound", and sometimes bla— er, attributed to Erich von Stroheim or some other German director.
Other possible explanations are that it meant "Minus Optical Stripe" or "Minus Optical Sound" or even "Motor Only Sync" or a half dozen other things. The truth seems to be lost in the mists of time, so don't let anyone bullshit you into thinking they have the definitive answer... unless they're Erich von Stroheim.
