They’re doubtless breaking out the champagne and caviar — or possibly Red Bull and M&Ms, now that Disney is no longer paying the bills — at the Weinstein Co. over my colleague Kyle Smith’s three-star review of “Factory Girl” and star Sienna Miller, whom he reports is “wincingly good” as doomed Andy Warhol protege Edie Sedgwick. This, of course, follows months of bad press, threatened lawsuits and reshoots for the biopic, which had an Oscar qualification run in Los Angeles back in December that netted no nominations.
