The yell was in the 70mm, 16mm, and 8mm mixes, but wasn’t on the 35mm mix or any home video mix until the SE.
I just checked the 70mm in-theater recording and the Yoda yell is not there.
Whoah. So that’s a 16mm mix difference that’s NOT also on 70mm. I was assuming 16mm differences were a subset of 70mm, but it appears there’s some Venn diagram complexity here. It also means the yell wouldn’t have been heard in a normal theatrical setting at all, but may have been heard in hospital/military venues where 16mms were shown, at home, or possibly in some odd broadcaster version.
