It's a match-up nobody could have ever imagined, but that just makes it an even more mouth-watering prospect as the unlikely lads of the Bengals look for one more upset against the star-studded Rams.
LA are favourites, playing in their home stadium and having a plethora of big names, but the Bengals have upset the odds all season long - making this Super Bowl run after previously winning just six games in two seasons.
Both teams have star QBs, both teams have star wide receivers and both teams have huge big-play ability - whoever wins this coin toss of a game will be a huge story in the NFL, and the wider world of sport.
As it's now a global game, over 100 million people will watch in the USA alone, but the game is broadcast to 180 countries in 25 languages and with more NFL games being played in the UK, Mexico and Germany later this year, this is just the start of a big global expansion.
And what better way than in what could be an epic Super Bowl contest to provide a proper Hollywood ending to a season packed with more tight finishes and more underdog upsets than ever before.
Let's take a closer look at one of the biggest games in sport.
Super Bowl LVI the lowdown
Where: SoFi Stadium, Los Angeles
When: Sunday 13 February, kick-off 23:30 (GMT)
How to watch on TV: BBC & Sky Sports
Half-time show: Eminem, Snoop Dogg, Mary J Blige, Kendrick Lamar & Dr Dre
The Super Bowl returns to Los Angeles for the first time in almost 30 years, but after the local market seemingly fell out of love with the NFL, the biggest game of the year is back to its roots, back to where it all began.
The Green Bay Packers beat the Kansas City Chiefs at the Coliseum in 1967 in what was then called the AFL-NFL World Championship Game.
That subtle title was never going to stick, and it was later renamed the Super Bowl after the phrase was used by Chiefs owner Lamar Hunt.
Now THAT is a name befitting of the occasion.
This will be the eighth time the Super Bowl has been held in LA - only Miami and New Orleans have staged it more - and it comes at a wonderful new $5 billion SoFi Stadium built by Rams owner Stan Kroenke...yes, the Arsenal Stan Kroenke.
A venue, a name, and two teams worthy of playing out such an occasion. Speaking of the teams, let's meet the contenders.
Meet the Bengals: A Hollywood ending for an underdog story?
The Bengals were 125-1 shots at the start of the season, but with second-year QB Joe Burrow proving to be a superstar, they've become a real force with huge big-play ability and an improving defensive toughness that just keeps them in games right down to the wire.
No team has ever won three play-off games by just one score, and their total winning margin of 13 points in the play-offs is the smallest ever - when a game gets close, this team doesn't flinch.
Meet the Rams: Star-studded LA going all in to win
Most teams cling on to their draft picks for dear life, but the Rams have gone the other way and have been wheeling and dealing them for a few years to bring in established star names and build this uber-talented roster.
The key being QB Matthew Stafford's blockbuster move from the doldrums of Detroit, but they also added a former Super Bowl MVP in Von Miller and one of the best wide receivers in the game in Odell Beckham Jr after his career nosedived in Cleveland.
A well-travelled Rams side have bounced around America from Cleveland to LA to St Louis and now back to the City of Angels, where they've splashed out on a new stadium and splashed out on new Hollywood stars. The pressure is now all on them to deliver.
Super Bowl head-to-head: Bengals vs Rams
The Rams have all the star names, but the up-and-coming Bengals could just have a few players who will become household names after Sunday and in the next few years.
So would you rather have the experienced Matthew Stafford or the young stud Joe Burrow as your quarterback? Head coaches Sea McVay and Zac Taylor know each other inside out, who has the edge?
Cooper Kupp was the best receiver in the league this season, but Ja'Marr Chase produced the best rookie numbers in NFL history, so who will be top dog on Sunday?
The Rams have Aaron Donald, Leonard Floyd and Von Miller as arguably the best pass rush in the league, but a collective defensive effort from the Bengals has twice thwarted Patrick Mahomes and his high-flying Chiefs attack.
Keys to victory: How can the Bengals and Rams win the Super Bowl?
Throughout the build-up to one of the biggest games in sport, we're always looking at just how each time can go on to win the Super Bowl, and there's one stand-out match-up between the Rams' defence and Joe Burrow that could decide the whole thing.
It's not the only key feature for deciding this contest though, as Matthew Stafford has issues under pressure, the Bengals have a star pass rusher of their own, and both teams need to find innovative ways of getting their playmakers the ball.
Super Bowl stats
- After 54 years with no team playing a Super Bowl at home, the Rams are the second on the bounce after the Buccaneers won in Tampa Bay last year.
- This is just the second time two QBs who were No.1 overall picks in the draft have met in the Super Bowl - with Joe Burrow and Matthew Stafford joining Payton Manning and Cam Newton from Super Bowl 50.
- The Bengals have played in two Super Bowls previous, losing both to the 49ers, while the Rams have won one of their four previous appearances.
- With Bengals head coach Zac Taylor aged 38 and opposite number Sean McVay 36, this is the youngest head coaching Super Bowl match-up of all time.
- If the Rams win, Sean McVay will be the youngest ever Super Bowl winning head coach, eclipsing Pittsburgh's Mike Tomlin who won aged 36 years and 323 days.
- The pre-match betting underdogs have won six of the last 10 Super Bowls.
- This is the first Super Bowl since 1975 not to have a first or second seed taking part. Both teams were seeded four in their conference so we'll have a fourth seed as Super Bowl champs for the first time since Baltimore did so in 2012.
