This 9.12 Boston Herald piece by Gayle Fee and Laura Raposa seems to offer the best shoe-leather reporting and thorough analysis as to why Robert De Niro recently walked off the Martin Campbell-directed thriller Edge of Darkness, which costarred Mel Gibson.

Boiled down, Campbell “repeatedly shot and re-shot a scene [in which De Niro’s] character tries to hit a ball out of a sand trap” at Gannon Golf Course in Lynn, Massachucetts. De Niro finally got sick of it — how many fucking times do I have to hit this fucking ball and knock sand into my shoes and into my eyes? — and said fuck it, fuck you, I’m outta here. (These aren’t quotes, of course — I’m just putting myself into De Niro’s golf shoes.)
