Final voting begins today for the 91st Oscars, and it probably isn’t a moment too soon for beleaguered Movie Academy officials who seem to have a new controversy to deal with every day. Ballots from the 8,176-or-so voting members will be due back next Tuesday at 5 PM PT in all 24 categories including Best Picture, which is the only one of them decided on a preferential basis where members must rank their favorites, from 1 being best to 8 being least favorite.
