LAS VEGAS – Warner Bros offered a glimpse of its eagerly anticipated Joker sequel at CinemaCon on April 9, as the Hollywood studio set out plans to build on the success of 2023’s blockbuster Barbie.

The presentation at the Las Vegas movie summit also featured footage from a long-awaited follow-up to 1980s classic Beetlejuice, plus British actor Robert Pattinson promoting a new science-fiction film from Parasite director Bong Joon-ho.

But the focus was on Joker: Folie A Deux, Todd Phillips’ sequel to a controversial original that won an Oscar for its star Joaquin Phoenix, and reinvented what is possible for superhero adaptations.

The 2019 Joker offered a dark, R-rated origin story for Batman’s future nemesis Arthur Fleck, and polarised audiences by presenting its murderous villain as a hero, even prompting fears it could inspire mass shootings.

Rumours have swirled around the sequel – out on Oct 4 – which adds Lady Gaga, one of the world’s biggest pop music stars, to its cast, and has been described as a musical.

Introducing a new trailer for the film, Phillips, 53, called his latest work “a film where music is an essential element”, adding that it “doesn’t really veer too far from the first film” in that sense.

“Arthur is weird and aloof and distant, all these things, but he has music in him, he has a grace to him,” said the American film-maker.

“That informed a lot of the dancing in the first film, so it didn’t seem like that big of a step, what we did here.

“It’s different, but I think it’ll make sense once you see it.”

The trailer showed Phoenix’s Joker meeting Lady Gaga’s Harley Quinn in an asylum, before the two seemingly plot their escape.

Other dreamlike sequences featured the pair dancing romantically on a moonlit Gotham rooftop, and putting on an elaborate stage show.

“I’ll tell you what’s changed. I’m not alone any more,” said the Joker in one scene.

Phillips also thanked movie theatre owners for standing by his first Joker film in 2019. It went on to gross more than US$1 billion (S$1.34 billion).

The annual CinemaCon movie industry summit is an opportunity for Hollywood studios to present their upcoming films to theatre owners from around the world.

The summit is being held as industry forecasts predict the annual global box-office haul will shrink, in part due to the impact of recent industry-wide strikes.

Actors and writers shut down hundreds of Hollywood movie and TV productions in 2023, leaving gaping holes in current release calendars.

The blow is just the latest in a difficult five-year period for the industry, which has yet to fully recover from the pandemic, and the rise of streaming.

As a studio, Warner enjoyed significant success with Barbie, the top grossing film of 2023, which earned US$1.45 billion.

But parent company Warner Bros Discovery, created by a 2022 merger, has seen its stock price plummet, even as mass layoffs ensued.

So, the stakes were high for the studio’s upcoming slate, which also included George Miller’s Furiosa: A Mad Max Saga, M. Night Shyamalan’s horror film Trap, and Kevin Costner’s new multi-movie western saga Horizon.

Costner, 69, promised his project, which involves back-to-back films hitting theatres in June and August, will take an unflinching look at the 19th-century settlers who fought tooth and nail to grab their share of the American West.

“That promise meant that we stepped on a whole group of people who had been here for thousands of years,” said the American actor.

“But that’s what happened. I don’t pass judgment because I don’t want to look down on people’s resourcefulness to create what they created here in America.”

Returning cast members Michael Keaton and Catherine O’Hara previewed Beetlejuice Beetlejuice, a sequel that director Tim Burton called a weird family reunion.

South Korean director Bong made his CinemaCon debut to promote science-fiction comedy Mickey 17 – his first film since Parasite (2019) became the only non-English-language movie to win Best Picture at the Oscars.

“With Bong doing it, it was a no-brainer,” said Pattinson, 37, who plays multiple characters in the movie, out in January 2025. AFP
