Oscars hosts rated: From Jimmy Kimmel to Ellen to Chris Rock
It's a job that's 91-years-old. Only thirteen people have done it since the year 2000. The shift lasts around three or four hours, but this year no-one's doing it.
Hosting the Oscars is a tough gig.
Kevin Hart was due to do it this year but has quit over homophobic tweets he sent ten years ago.
But who's done the best job of fronting the ceremony recently?
We've looked at the Academy Awards from the last 10 years and got Radio 1 and 1Xtra's film critic, Ali Plumb, to give the hosts a rating out of 5 stars, movie review-style.
We'll also jog all of our memories by reminding you which film won best picture in each year.
2009 - Hugh Jackman
Best picture was... Slumdog Millionaire
Big Hugh is a versatile man. Action, romance, drama, singing and dancing, he can do it all.
"I just think Hugh Jackman's ferocious enthusiasm screamed off the screen," Ali says.
Hugh's big musical medley with Beyonce had the crowd on their feet. A BBC article from the time noted that Hugh didn't get much time on stage himself, but Ali says he liked that.
"For me as a viewer, if you're not a comedian, I'd rather you just set things up and got on with it.
"Hugh isn't Mr Jokes, so I was very happy with him doing the intro and getting cracking. The Oscars have a problem with speed and with frankly boredom, so the quicker they can do it, the better."
Ali's rating: 4 stars
2010 - Steve Martin and Alec Baldwin
Best picture was... The Hurt Locker
You might know Alec Baldwin best for appearing in the recent Mission: Impossible films or for playing Donald Trump in Saturday Night Live.
He and comic actor Steve Martin aren't a classic double act.
"I thought their delivery was game and enjoyable, but the jokes were a little bit flat," Ali says.
"One for example is that they go 'Oh look, it's the director of Avatar, James Cameron. We're both going to put on our 3D glasses now.' Haha, grandad.
"They're both amazing, but also - a bit fresher than this please."
Ali's rating: 3 stars
2011 - James Franco and Anne Hathaway
Best picture was... The King's Speech
Sometimes one host just isn't enough, and the Academy goes for two. In Ali's view, it didn't work.
"It was a train wreck from the very beginning.
"The audience didn't like it, both at home and in the Kodak Theatre. It felt weird, it was weird. Never again. Never, never again. Even just thinking about it, I feel my skin crawling."
Ali's rating: 1 star
2012 - Billy Crystal
Best picture was... The Artist
You might know him best as the voice of Mike Wazowski in Monsters Inc. He's an acting and comedy legend and this was his ninth time hosting the Oscars.
"Billy Crystal is one of those people that the Academy press the red button for whenever they really need someone last-minute," Ali says.
"It was OK."
Ali's rating: 3 stars
2013 - Seth MacFarlane
Best picture was... Argo
Family Guy creator Seth MacFarlane hosted for the first time in 2013, bringing his trademark crude humour to the role.
Seth sang a song about female nudity in films called We Saw Your Boobs, which Ali says was "icky" and made him feel uncomfortable.
A lot's changed since 2013, and following the Harvey Weinstein scandal and the MeToo movement, there's no chance that sort of song could be performed at the Oscars now.
Overall, he thinks Seth was "a bit of a flop" as a host.
Ali's rating: 2 stars
2014 - Ellen
Best picture was... 12 Years a Slave
This was Ellen's second time hosting and Ali says it was "really enjoyable".
"It was witty, it was very inside Hollywood. It was clever and confident and snappy and she's just such an assured presence."
Ellen did things you'd do at home with friends: taking group selfies, ordering pizza. She's just like you and me.
Except she eats pizza with Meryl Streep and Brad Pitt - and her selfie with Jennifer Lawrence, Bradley Cooper, Lupita Nyong'o and a load of other stars became the most retweeted image in Twitter's history.
Like I said, just like you and me.
Ali's rating: 4 stars
2015 - Neil Patrick Harris
Best picture was... Birdman or (The Unexpected Virtue of Ignorance)
NPH, as some fans call him, is probably best known as Barney Stinson from How I Met Your Mother.
Ali says Neil is remembered for a Birdman skit where he appeared on stage in his underwear, but points out "if you've forgotten that best picture winner, it will be a very weird thing to see on your screen".
He says Neil was "pretty good" but "not great".
Ali's rating: 3.5 stars
2016 - Chris Rock
Best picture was... Spotlight
This was the main year of the #OscarsSoWhite hashtag, because for the second year in a row, only white actors and actresses were nominated for the top awards.
Chris Rock was hosting, and there was no way he was going to avoid the issue.
"Chris Rock is divisive because either you really enjoy his edgy, sparky, difficult humour or it just doesn't work for you," Ali says.
"I personally really liked it... I could feel people not connecting with him perhaps as much as they should have.
"He's not for everyone, but I did think he was pretty brilliant."
Ali's rating: 4 stars
2017: Jimmy Kimmel
Best picture was... Moonlight
Probably the most memorable Oscars of recent years, all because of a BIG mix-up with an envelope.
La La Land was awarded best picture by mistake, when the real winner was Moonlight. Awkward.
"Honestly, all I can remember is the big cock-up, so whether he was good or bad is irrelevant. It's honestly got to be a one star. No offence to you Jimmy."
Ali's rating: 1 star
2018 - Jimmy Kimmel
Best picture was... The Shape of Water
"It was just a bit meh. And you don't want meh," Ali says.
"He should be better than this. He's very unfortunate. I think what he did in 2017 was actually pretty good until what happened. And it's not fair that he felt almost compelled to come back for 2018."
Ali's rating: 2 stars
Who does Ali think should host the Oscars?
"Will Smith. He'd be really good fun. He could really bang the drum for #OscarsSoWhite if he wants.
"In fact, I've been pitching with Ace (from 1Xtra). We want to have the whole Smith family as the hosts. I want all of them on and I want it to be a big family affair. Eccentric, loveable. Singing, dancing: the lot."
