Richard Dreyfuss talks about the time Murray attacked him...
... and he talked about it well before this kerfuffle. This is an interview from 2019, where Dreyfuss talks about the time Murray yelled at him, threw a heavy ashtray at him, and tried to punch him. He missed with both the fist and the ashtray, so do you think he might have had a drink or ten?

Anyway, I once saw a co-worker be fired on the spot for throwing a stapler at someone and missing, I wonder if Murray did something like that on the set... and found that Hollywood is no longer willing to tolerate that shit.
