So from what I've been able to gather:
- Multiple cast members were vocal about their distaste for the rewritten dialogue, including Jeremy Irons who described them as '****ing stupid' and went off to his trailer to rewrite them himself
- Whedon was particularly unpleasant to Gadot, so much so that afterwards one of the producers forbade him from addressing the cast without a studio representative present
- Whedon refused to address Ray Fisher's concerns about his character, his stance being that he didn't take notes from Robert Downey Jr., so why would he extend that courtesy to Fisher?
- Both Gadot and her stunt double refused to do the boob faceplant scene, resulting in Whedon locking the latter in a room and threatening to end her career
- Affleck tried to convince the cast to walk out (but to no avail, obviously)
- During Gadot's final ADR session, Whedon threatened to interfere with Wonder Woman 1984 just as he did Justice League
