Tonight is the sequel of all sequels as two incredibly talented heavyweight fighters enter the ring for a rematch.

The bout between Oleksandr Usyk and Tyson Fury in May delivered and then some, but will the rematch also live up to the hype?

I've been mulling over it this week and couldn't help but start thinking about movie sequels and which ones (if any) are better than the initial release.

So now seems like the perfect time to throw that question out to a wider audience.

What film sequels are better than the original?

Ringwalk timings in Saudi have been a bit hit and miss in the past 12 months. Some fights have begun well after midnight while others have started closer to 22:00.

Organisers in Riyadh this time are aiming for the earlier end of that spectrum.

The first fight took place at 16:00 GMT.

Usyk and Fury's ringwalks are targeted for 22:15, meaning the fight will probably startaround 22:30.

We're just about to get under way in the bout between Dave Allen and Johnny Fisher.

BBC Sport spoke to Allen ahead of his 32nd professional fight.

"I don't want to live a life of regret," said Allen. "I want to know how good I am."

Before we get to deep into build up for the rematch, it's probably worth a little refresher on how the meeting in May between Oleksandr Usyk and Tyson Fury played out, right?

Queensberry's Frank Warren, Matchroom's Eddie Hearn and former cruiserweight Tony Bellew take a look back at how it all unfolded.

We've already had plenty of action at Kingdom Arena in Riyadh this evening and I'll update you on how those fights have played out shortly.

British heavyweight rivals Johnny Fisher and Dave Allen have just made their walks to the ring.

We've got two more bouts to follow Fisher and Allen and then it's the main event.

• Serhii Bohachuk v Ishmael Davis - light-middleweight
• Moses Itauma v Demsey McKean - heavyweight

Here we go. These are the nights boxing fighters, fans and reporters live for. The biggest heavyweight bout on the planet between the two greatest of their era.

Just one point separated them in May. After such a gruelling contest, Tyson Fury and Oleksandr Usyk probably left a bit of themselves in the ring six months ago.

Tonight will come down to which man has more left in the tank.

The result of this fight is as unpredictable as Fury's antics. Strap in, though, because whatever happens, you are guaranteed to be entertained.

Just four sleeps until Christmas but more importantly it's just a few hours until we get to see Oleksandr Usyk and Tyson Fury go at it for a second time.

There is no undisputed title on the line tonight, Usyk vacated his IBF strap after beating Fury in May, but the Ukrainian's WBA (Super), WBC and WBO belts are on the line in Riyadh, Saudi Arabia.

Will Usyk prevail again? Or will Fury gain his revenge?
