The Queen "Bohemian Rhapsody" movie was fun, but now my head is all stuck in the '70s & 80's again :^).
The technical aspects of the movie were remarkably good for the most part, the "Live Aid '85" recreation used Malcolm Hill (M4 like) speakers for the side fills, and huge dual 15" 3-way floor monitors which made me curious as to who had done audio production for the event, back in the days before Clair bought up all the competition.
Sure enough, Malcolm Hill Associates had provided production for the event, but the floor monitors in the film version "cheaped out" on the HF horn and mid speaker, and undersized the LF ports.
In the movie, Queen's manager lifts a pair of LR faders (which typically would have been stage side fills) about 10 dB above the taped off "limit" with no feedback...
It's historically interesting to find that the Leq SPL for Queen was also around 10 dB louder than the softest set, 100.7 db(A) for their performance, the lowest set averaging 90.5 dB(A) at the mix position, 130 feet back from the speakers at 8 foot high.
