Obviously they can't erase Spacey, Polanski, Allen etc. from broadcasts because they are Oscar winners in BP winning films or close to it but who is someone that maybe looking into a crystal ball won't see getting ever mentioned or having clips shown - maybe ever again?
Gig Young I guess has been sort of erased because of that (apparent) murder-suicide but he's not nearly as necessary as the 3 above and I wouldn't have noticed if they ever showed him or who even knows that story...........Weinstein films could still have clips shown I'd guess, but he's out I'm sure.
Did it ever happen otherwise and if not...........will it?
They've shown all winners in montages before. Gig Young and Emil Jannings featured in the 2002 ceremony's montages, and even Kevin Spacey appeared in 2017's, right in the immediate aftermath of his controversy.
I bet you they will never show Shakespeare in Love’s Best Picture win in a telecast past a clip of Harrison Ford saying “the winner is Shakespeare in Love”). I’m certain Weinstein has been scrubbed clean and it’ll be easy because he only won once.
