Possible snub: “Sound of Metal” Possible surprise: “News of the World” Linda May, left, and Frances McDormand in “Nomadland.” (Searchlight Pictures) Analysis: The Producers Guild dropped its list of 10 best picture nominees on Monday. The Oscars is in its final year of its fluctuating slate that has always numbered either eight or nine movies. So that’s bad news for at least one PGA nominee, probably “Borat Subsequent Moviefilm,” as the academy owns a dispiriting history of ignoring comedies. The academy also hasn’t nominated an animated movie since abandoning its fixed list of 10 nominees (which, thankfully, returns next year), likely consigning “Soul,” one of the year’s most ambitious and imaginative films, to the ghetto known as “best animated feature.” It’s possible that the entertaining Tom Hanks western “News of the World” could find its way in, though it was ignored by the PGA, a group more inclined than the academy toward rewarding big studio pictures.
