HOLLYWOOD — Saturday’s final promotional event for a boxing match featuring undefeated Terence Crawford was packed into the courtyard outside the TCL Chinese Theatre and felt like a blockbuster movie.

“Jurassic Park” to be exact.

No expense was spared for the first international presentation under the umbrella of Riyadh Season, which aims to market the Kingdom of Saudi Arabia through combat sports.

Like the dinosaurs in Steven Spielberg’s adaptation of Michael Crichton’s book, everyone expects the entertainment at BMO Stadium’s fist-themed park to turn violent.

Crawford, who is seeking a title in the fourth weight class, faces Uzbekistan’s Israel Madrimov, the WBA and WBO interim 154-pound champion, in his final fight.

This is Crawford’s (40-0-0, 31 KOs) first fight since stopping Errol Spence last summer to become the undisputed cruiserweight champion and one of the first names mentioned in pound-for-pound discussions.

The 36-year-old Nebraska native, who has started to gain weight again, said she feels stronger and more energetic since putting less stress on her body to lose weight.

“Terence Crawford is one of my favorite boxers and one of the best boxers in the world,” said the 29-year-old Madrimov (10-0-1, 7 KOs). “I’m very excited to have the opportunity to make this announcement and God willing I will.”

Tickets sold slowly at first, with brokers snapping up thousands of seats and offering them at prices fans were not prepared to pay.

This week, as the big-money promotion ramped up (an open workout and bouts were held Wednesday at the Santa Monica Pier; cars around the city were covered with fliers displaying the Saudi Arabia and Riyadh Season logos above the fighters’ heads; and a final press conference was held that blocked the sidewalks), sales have skyrocketed.

Organisers said around 21,000 people were expected to attend the open-air event, which will also feature rapper Eminem.

Boxers welcomed a slice of the big money pie that had turned football upside down and thrown professional golf into chaos with the birth of LIV.

It comes six years after the assassination of Saudi dissident journalist Jamal Khashoggi, in which the CIA concluded that the country’s crown prince, Mohammed bin Salman, ordered the killing, creating a diplomatic rift for the oil-rich country that has since been diffused to some extent by its massive investment in sports.

Flirting with the dangers that Dr. Ian Malcolm warned about in the classic first installment of the “Jurassic Park” series, boxing channels, distributors, fighters and promoters have chosen to unite around Saudi Arabia’s plan to centralize the sport.

Malcolm, a mathematician specializing in “Chaos Theory” played by Jeff Goldblum, could have written a thesis on boxing, which has long been characterized by chaos and unpredictable outcomes.

But if Turki Alalshikh implements his plan, this will no longer be the case.

Alalshikh, who played a leading role in increasing Saudi Arabia’s interest in combat sports and is also the chairman of the Saudi Arabian General Entertainment Authority, said he aims to revive boxing rather than revive the dinosaurs.

Of course, rumors that boxing has ended with carbon dating back to the Jurassic Period have been exaggerated due to the constant filming of fighters. Without the freezing that Alalshikh suggests, generations of fighters have managed to inspire interested audiences.

Saturday’s card brings together a mix of fighters signed to various promoters, including Matchroom, PBC, Top Rank and Golden Boy. Technically, the Saudis aren’t promoters at all. They are not licensed by the California State Athletic Commission, but were billed as such in April when the August 3 date was first announced.

The chief promoter working with the California State Athletic Commission is actually Eddie Hearn of Matchroom, who has spoken highly of Alalshikh’s impact on the sport of boxing.

On Saturday’s $79.99 pay-per-view event, Isaac Cruz (26-2-1, 18 KOs) defends his WBA super lightweight world title against Jose Valenzuela (13-2, 9 KOs), also of Mexico.

Former unified heavyweight world champion Andy Ruiz (35-2, 22 KOs), who lost his title to Britain’s Anthony Joshua in Saudi Arabia in December 2019, will face New York’s Jarrell “Big Baby” Miller (26-1-1 22 KOs).
