Oscars 2018: All you need to know about this year's best picture nominees

Nine films have been nominated this year for the Academy Award for best picture, the biggest prize on Oscar night.

It will be the last statuette presented on Sunday 4 March at this year's ceremony, held as ever at the Dolby Theatre in Hollywood.

Last year saw an astonishing mix-up that led to La La Land being wrongly named the winner ahead of Moonlight, the rightful Oscar recipient, and organisers will be hoping things go more smoothly this year.

What did the critics say? "Director Joe Wright takes history at its most momentous, wraps it around a figure who couldn't be more iconic, and places this rich but heavy package almost entirely in the hands of Gary Oldman... If Oldman doesn't get to flick a V on Oscar night, we'll eat our Homburg hat." Dan Jolin, Empire

What did the critics say? "This is not a film that dwells on style. It is a film possessed by a fear that style alone, or the quest for it, can cramp the soul... Yet, despite everything, we continue to cling to the problems and pursuits of this obsessive dandy. And why? Simply because there has never been an actor as obsessive as Day-Lewis." Anthony Lane, New Yorker

What are its chances? Sew sew. The real strength here, as always, is Day-Lewis.
