Tyson Fury and Deontay Wilder fought out a thriller in Los Angeles 14 months ago and the second instalment of a planned trilogy will be battled out in Las Vegas on Saturday night.
The WBC heavyweight belt goes on the line at the MGM Grand, which long ago jumped ahead of Caesars Palace as the hottest spot to see elite fighters pull on the gloves in America's gambling capital.
Within the vast urban sprawl of the hotel and casino's grounds sits the Garden Arena, where legends have been made and demolished.
Neither Fury nor Wilder is a stranger to the MGM Grand boxing ring, but neither man has had a career-defining fight there yet.
Fury versus Wilder II could be a classic. Their stunning draw in LA leaves all to fight for.
Here is a look at five of the most dramatic and memorable blockbuster showdowns in the 26-year history of the big-fight coliseum.
5. George Foreman beat Michael Moorer, KO, November 1994
Before he became a grill pan hype man, Foreman was frying rivals in the ring.
The veteran rolled back the years on one of the MGM Grand's first big bills, after fighting for permission to even step into the ring. With the 45-year-old having not had a bout in almost 18 months, the WBA initially refused to sanction the contest, but Foreman went through the courts to get the go-ahead, and it was worth the effort.
The man who lost to Muhammad Ali in 1974's Rumble In The Jungle caused a seismic stir in Sin City with this 10th-round knockout victory, landing the WBA and IBF heavyweight titles as he became the division's oldest-ever champion. He had been outboxed for much of the fight, but Foreman found his punching power when it mattered.

4. Juan Manuel Marquez beat Manny Pacquiao, KO, December 2012
This was the final stanza in a Vegas quadrilogy for Marquez and Pacquiao, with a draw and two Pacquiao points victories in their previous clashes setting up another slice of MGM Grand history.
Amusingly, their second fight had been dubbed 'Unfinished Business', so the promoters needed to ramp up the anticipation for this one, pre-emptively titling it 'Fight of the Decade'.
It went a long way towards living up to that billing, earning Ring Magazine's Fight of the Year gong after Mexican Marquez turned the tables on his Filipino rival, driving a brutal right hand into Pacquiao's jaw in the dying seconds of the sixth round.
The fight-defining shot from the 39-year-old capped a sensational contest in which both men had been in trouble, and down went Pacquiao with a thud to the canvas.
Promoter Bob Arum suggested they go at it again in a fifth fight, but that never materialised. Marquez retired as a five-time world champion, his titles coming across four weights.
This was not a title fight, but the punch that collapsed Pacquiao forms a huge part of the Marquez legacy.

3. Floyd Mayweather beat Oscar De La Hoya, split points decision, May 2007
Anticipation for this light middleweight barnstormer reached fever pitch in the United States, where almost 2.5million households signed up for $55-a-throw pay-per-view television coverage, a record number.
Broadcaster HBO produced a four-episode mini-series building up to fight night, and there was also the saga of which corner Mayweather's father, Floyd Mayweather Sr, would be in, given their estrangement and his availability as a top-level trainer.
The answer was ostensibly neither corner in the end. Mayweather Sr reportedly priced himself out of a role with De La Hoya, and Mayweather was primed for the showdown by his uncle, Roger Mayweather.
The hype machine was pumping out hyperbole by the time the fight began, and the fact it turned out to provide huge entertainment was testament to the focus of both fighters.
Mayweather was given 116-112 and 115-113 verdicts, with De La Hoya 115-113 on the other, and the winner's verdict that it was "easy work for me" flew in the face of abundant evidence.
Floyd Mayweather Sr, showing not a jot of family loyalty, surmised that De La Hoya would have deserved the win.
2. Frankie Randall beat Julio Cesar Chavez, split points decision, January 1994
It was opening night at the Garden Arena, six weeks after doors to the MGM Grand hotel swung open for the first time.
The WBC super lightweight belt was on the line, Don King was the promoter pulling the strings, and for its outrageous shock factor, Randall's victory over Chavez that night ranks as one of the venue's greatest triumphs.
Chavez had been described months earlier by Sports Illustrated as "the world's greatest fighter", and he headed into this bout with 89 wins and one draw from 90 professional encounters.
Randall dominated the early stages but was pegged back by Chavez, only for low blows from the Mexican to result in two points being deducted by referee Richard Steele - the telling factor.
Chavez would have won a split points decision, rather than lost that way as he did, had he not been penalised, and later said he was "very upset" with Steele.
A bizarre rematch went Chavez's way. In a highly unusual outcome, an eight-round split decision favoured Chavez when an accidental headbutt from champion Randall left the challenger unable to continue.
1. Evander Holyfield beat Mike Tyson, TKO, November 1996; Holyfield beats Tyson, by disqualification, June 1997
Tyson effectively set up camp at the MGM Grand in the second half of the 1990s, having spent a large chunk of the first half behind bars after a rape conviction. He and promoter King landed a mega-money six-fight deal with the venue, after Tyson's comeback began there with a first-round win, by disqualification, over Peter McNeeley in August 1995.
A March 1996 dust-up with Britain's Frank Bruno was a major money-spinner, but nothing touched the prospect of a long-awaited collision with Evander Holyfield for commercial potential.
Holyfield and Tyson had been due to clash at Caesars Palace in November 1991, but a rib injury suffered by Tyson, followed by his incarceration, put paid to that.
Their 1996 showdown was billed as 'Finally', and the first fight – though now often overlooked because of what followed – was a monumental contest in heavyweight history, Tyson succumbing to just the second defeat of his professional career.
It featured thudding head collisions and the sight of Tyson being outboxed by the underdog until enough was enough for referee Mitch Halpern, who stepped in to stop the fight in the 11th round.
Halpern was kept busy that night but was prevented from officiating the rematch seven months later after a complaint from the Tyson camp, with Mills Lane stepping in at late notice.
It was to prove extraordinary, as Tyson bit both of Holyfield's ears during clinches in round three, spitting out a chunk of cartilage onto the canvas at one stage before outrageously claiming a punch had caused the injury.
Lane said it was a "b******t" explanation and disqualified Tyson, who was banned indefinitely. After a year, 'Iron Mike' had his licence back, but his glory days were over, those bites now more famous than any punch he ever threw.
What happens in Vegas no longer stays in Vegas. Instead, it is beamed around the world, with Fury and Wilder next under the spotlight.
