Lots of folks don't pay a lot of attention to the internecine dramas of Hollywood labor strife until it starts postponing new episodes of Grey's Anatomy, so not everyone has been following the extraordinary bitterness now marking the internal battles within the Screen Actors Guild. Remember, this isn't the negotiation between the actors and the studios; this is intraunion infighting. A 30-hour filibuster? Hollywood actors openly calling each other "children" on one side and "petulant and foul-mouthed" on the other? Circulating e-mails suggesting nobody vote to give a SAG award to anyone who's opposed a strike? By the time awards season gets fully in gear, they may need to hire bigger bouncers at the after-parties in case a couple of guys in tuxes start smacking each other around. Shocking, really.
