Nominations for the 2024 Oscars will be announced on Tuesday, after a huge year for cinema which saw Barbie and Oppenheimer dominate the box office.

Poor Things, The Holdovers and Killers of the Flower Moon are also expected to feature heavily when the nominations are announced from 13:30 GMT.

Cillian Murphy, Emma Stone, Robert Downey Jr and Da'Vine Joy Randolph are all likely to score acting nominations.

Jimmy Kimmel will host this year's ceremony from Los Angeles on 10 March.

The Barbenheimer phenomenon, a viral trend which saw thousands of fans book tickets to see both films on the same day last summer, makes this year's Oscars far more accessible than usual.

While several Academy Awards ceremonies in recent years have recognised films which had little breakthrough with the general public, producers will be hoping Barbie and Oppenheimer's likely inclusion will result in a surge in interest and viewers.

Which films are competing for best picture?

After a rule change a few years ago intended to widen the field, the best picture category now has a guaranteed 10 slots available.

There is general consensus that Oppenheimer, Barbie, Poor Things, Killers of the Flower Moon and The Holdovers will all score nominations.

Anatomy of a Fall, Maestro, The Zone of Interest, Past Lives and American Fiction are also seen as hot favourites and very likely to compete for the Academy's most prestigious prize.

But there are plenty of other contenders which could easily spring nominations in the top category, such as The Color Purple, Society of the Snow, All of Us Strangers and May December.

In recent days, there has also been a last-minute campaign - similar to the one that netted Andrea Riseborough a surprise acting nomination last year - for Origin to be recognised at the Oscars, after it missed out at a string of precursor ceremonies.

Who's in the acting race?

After a slightly weaker field in 2023, this year's best actor category is extremely crowded and competitive.

The frontrunner is Paul Giamatti for The Holdovers, a film which sees him play a grumpy teacher who must stay in his boarding school over Christmas to supervise the pupils who aren't going home for the holidays.

Cillian Murphy is also in the race for his portrayal of theoretical physicist J Robert Oppenheimer, while Bradley Cooper could be recognised for his performance as composer Leonard Bernstein in Maestro.

Meanwhile, Rustin's Colman Domingo is a strong contender for his depiction of civil rights activist Bayard Rustin, and Jeffrey Wright could be recognised for his role as a frustrated author in American Fiction.

Other possible but slightly less likely contenders include Killers of the Flower Moon star Leonardo DiCaprio, Saltburn's Barry Keoghan, The Iron Claw's Zac Efron and Andrew Scott for All of Us Strangers.

The best actress category is just as busy. Lily Gladstone will likely be recognised for her role in Killers of the Flower Moon as an Osage woman living in 1920s Oklahoma who must deal with efforts by white settlers to take advantage of their land for oil.

Poor Things star Emma Stone will almost certainly be nominated for her performance as an infant whose brain has been transplanted into the body of a grown woman, who then goes on an adventure across the world.

Sandra Hüller could be recognised for playing a mother accused of murdering her husband in Anatomy of a Fall, while Maestro's Carey Mulligan is likely to be one of the few British nominees for her portrayal of Leonard Bernstein's wife Felicia Montealegre.

The Academy may well include Margot Robbie for Barbie, the monster box office hit which she also produced, Past Lives star Greta Lee for her role as a woman who reconnects with her childhood sweetheart, or Nyad's Annette Bening for her portrayal of record-breaking swimmer Diana Nyad.

There's also still a chance that The Color Purple star Fantasia Barrino could make it in, as could Priscilla's Cailee Spaeny for her portrayal of Priscilla Presley.

What about the supporting categories?

The Holdovers star Da'Vine Joy Randolph is the safest bet of all the acting categories - she has dominated at all the precursor ceremonies and is very likely to win best supporting actress at the Oscars.

She could be joined in the category by The Color Purple star Danielle Brooks, Oppenheimer's Emily Blunt, Nyad's Jodie Foster and Ferrari's Penélope Cruz.

Other possible nominees include Julianne Moore of May December, Saltburn's Rosamund Pike and Barbie's America Ferrera.

The supporting actor race will almost certainly be led by Oppenheimer's Robert Downey Jr. But there is competition from Barbie's Ryan Gosling, American Fiction's Sterling K Brown and May December's Charles Melton.

Meanwhile, two actors from Poor Things - Mark Ruffalo and Willem Dafoe - could be recognised, and it's never a good idea to bet against Robert De Niro, who appeared in Killers of the Flower Moon.

What about the directors?

Several Oscars stalwarts released films this year and will almost certainly show up in this category - such as Martin Scorsese for Killers of the Flower Moon, and Christopher Nolan for Oppenheimer.

There could also be recognition for Greta Gerwig for Barbie, Jonathan Glazer for The Zone of Interest and Yorgos Lanthimos for Poor Things.

Otherwise, spots could go to Justine Triet for Anatomy of a Fall, Alexander Payne for The Holdovers, Bradley Cooper for Maestro and potentially even Celine Song for her accomplished directorial debut Past Lives.

Two of the last three winners of best director have been women - although last year it was an entirely male set of nominees.

Why is best original song so crowded?

In a word, Barbie. The film's soundtrack was almost as ubiquitous last summer as the movie itself.

Three different songs from the film are in contention for the musical prize this year - Billie Eilish's What Was I Made For?, Dua Lipa's Dance the Night and I'm Just Ken performed by actor Ryan Gosling.

However, according to Oscar rules, only two songs from the same film can be nominated - so at least one of the above will miss out.

The remaining slots could be taken by the likes of Lenny Kravitz's Road to Freedom from Rustin and It Never Went Away from American Symphony, written by Jon Batiste and Dan Wilson of US rock group Semisonic.

But don't bet against competition from songs lifted from the soundtracks of The Color Purple, Flora and Son, Flamin' Hot and The Hunger Games: The Ballad of Songbirds and Snakes - the latter could see Olivia Rodrigo nominated for Can't Catch Me Now.
