The Neighbors' Window is about a middle-aged woman whose life is shaken up when a couple of younger people move in over the road.

Adding: “It can help us to notice other people".
So throw those curtains wide...

"This is really light," he adds as he lifts the statue. "It's supposed to be heavy."
"I dedicate this to all indigenous kids in the world who want to do art," says the director, who is from New Zealand. "We are original storytellers and we can make it up here."
Jojo Rabbit, set during World War Two, tells the story of a young boy who is an aspiring Nazi and speaks to an imaginary version of Hitler. His views are challenged when he discovers his mother is hiding a Jewish girl in their home.

Earlier tonight, on the red carpet, Waititi said there's been "a resurgence of hate and intolerance" in the world of late.
"Sadly we need to teach lessons in how to be a good person."

It's very rare for a foreign film to win in this category. Director Bong Joon-ho described the film-making process as a "lonely" one, via a translator.
He then thanked his wife and the actors.
They were given their award by Diane Keaton and Keanu Reeves who seemed to be having a right hoot.
Diane recalls how they briefly dated in the 2003 film Something's Gotta Give.
Idina Menzel takes to the stage for the night's first performance from a best original song nominee, Into the Unknown.

"We have a firm belief that representation matters deeply, especially in cartoons," says producer Karen Rupert Toliver.
The film tells the story of a father who tries to do his daughter's hair for the first time.
The team dedicate the award to Kobe Bryant, the basketball star who died in a helicopter crash last month.

Awwwe. They certainly did for us.

It's the first acting Oscar for Pitt. And it's not a surprise that he's won - he's been the favourite throughout awards season.
"Thank you to the Academy for this honour of honours. This is about Quentin Tarantino, you are original, you are one of a kind," he says, paying tribute to the director.
"Leo, I'll ride on your coat tails any day," he jokes - shouting out his co-star in the film Leonardo DiCaprio.
"This is for my kids, who colour everything I do, I adore you," he concludes.

Image source, Getty ImagesComedians Steve Martin and Chris Rock are delivering the opening monologue, in the absence of a host.
In a segment packed with jokes, the pair say they're hoping there won't be a repeat of the envelope mix-up of 2017.
Martin jokes that apparently "the Academy has switched to the new Iowa Caucas app" to stop this happening again.
Chris Rock spots Martin Scorsese in the audience and quips: "I loved the first season of The Irishman," a reference to the film's 3.5-hour running time.
Addressing the lack of black actors nominated, Rock - after spotting Mahershala Ali in the crowd - said: "He's got two Oscars. You know what that means when the cops pull him over? Nothing!"
Then on Cynthia Ervivo, who portrayed the former slave-turned-abolitionist Harriet Tubman, he added she "did such a good job hiding black people that the Academy got her to hide the black nominees."
Image source, ReutersTo kick off proceedings, Janelle Monae has taken to the stage to perform A Beautiful Day In The Neighborhood.
That's the title song from the film of the same name, which has netted Tom Hanks a nomination tonight for best supporting actor.
She pops a top hat on Tom's head, then segues into one of her own songs, Come Alive, which sees her joined by Billy Porter as it turns into a duet.
The ceremony is officially under way!

Image source, ReutersThe Grammy-winner will perform later - possibly her new Bond theme - and she's described it as a "life goal" to be at the Oscars.
A short while ago she was quizzed about her favourite films on US TV by Billy Porter.
"I always loved scary stuff," she said, name-checking the movie We Need to Talk About Kevin.
Ferris Bueller's Day Off is hardly scary but it's another one of her faves.
That'll be some of you lot tomorrow probably if you follow our coverage until the bitter end.
Image source, AFP/Getty ImagesSir Sam Mendes has just been explaining a little more about the one-camera technique you'll have heard so much about in his war film 1917.
He said he "wanted people’s eyes to be able to wander across the landscape" of no-man's land.
"The action is unconventional in the movie; the first two action sequences involve a rat and a plane" he joked.
It's a pretty frightening CGI rat as well, if you haven't seen it yet.
Mendes then lost us a bit to be honest when he started talking about it being both an "objective and subjective camera".
So if you have a film studies degree and could explain, please get in touch.
Brad Pitt is the favourite to win best supporting actor tonight for his performance of Once Upon a Time in Hollywood.
For most viewers, more important than the award itself will be hearing his acceptance speech.
Pitt has aced his speeches at other ceremonies this season including the Golden Globes, Baftas and Screen Actors Guild awards, with just the right amount of self-deprecating humour.
Image source, ReutersIn Once Upon a Time in Hollywood, Brad plays the stuntman Cliff Booth.
Hes just told journalists he had a stuntman for the stuntman role.
"I love a stuntman," he laughted.
"'Please go as hard as you can, I'll be in the trailer having a coffee!'"

Natalie Portman's dress is embroidered with the names of some of the female directors who could have been nominated this year, but weren't.
We had to zoom in quite a lot, but the surnames on the little black strip on her gown include [Marielle] Heller, [Greta] Gerwig and [Lulu] Wang.

Joaquin Phoenix's unusual Oscar campaign
After cleaning up at every major movie bash so far this award season, Joaquin Phoenix looks odds-on favourite to be named the Oscars' best actor.
But his all-conquering role in Joker has been no laughing matter for the star, who has used his acceptance speeches over the past month as a platform for various campaigns.
One of those issues is climate change, and days before the Academy Awards he is the star of a new short film, part funded by Extinction Rebellion.
Watch above to see how Joaquin led a very different Oscars campaign.
Image source, AFT/GettyRobert De Niro and Al Pacino have just been talking about what it's like working with the veteran director Martin Scorsese.
De Niro, of course, has come up through the ranks with his fellow New Yorker on classic movies like Mean Streets and Goodfellas.
Fun fact though: The Irishman, which is up for best picture, is the first time that Scorsese and Pacino have worked together.
Who knew?
Pacino has just told US TV that the director basically gave him free reign on the film to make the character his own.
"He guides you through the role and allows you to do whatever you feel like doing," said Pacino.
"You're comfortable that he will catch you if you fall".
"You take more chances," he added.
Booksmart stars Kaitlyn Dever and Beanie Feldstein don't need any press photographers on the red carpet, they can take care of their own pictures.
Top marks all round.

Iconic behaviour.
