There are varying accounts as to what happened, the first being from The Movie Blog. According to the site, Bill Murray stopped mid-scene and pointed to Drew Barrymore, Cameron Diaz, and Lucy Liu in succession while saying, "I get why you're here, and you've got talent, but what in the hell are you doing here? You can't act!" Liu then allegedly "attacked" Murray by "throwing wild punches" and the actors had to be separated while they "lobbed verbal hand grenades at each other."
According to production assistant Shaun O'Banion (via the Daily Mail), the argument actually stemmed from Murray rewriting a "bunch of scenes without telling anyone" and putting the new pages in everyone's trailers. "Murray was like, 'I'm making it better, ok? You've got like, 16 writers on this thing...' and Lucy spoke up, saying something like, 'This is way out of line,'" O'Banion tweeted. "Murray turned and said, 'I don't know what you're complaining about. I have you more lines. I mean... look who you're in with here. You're from TV... and this is the big league.'"
Liu allegedly didn't react fondly to that comment, and shouted obscenities at Murray before running off stage crying. "No punches were thrown. At least not physically," O'Banion wrote. "He later apologised [sp] though not entirely sincerely in my honest opinion."
