The Hollywood scene is buzzing with uncertainty as CinemaCon rolls around this year. This event, held in the massive Colosseum theater at Caesar’s Palace in Las Vegas, is where studio bigwigs share their upcoming movie plans with theater owners. It's also a time when some execs might be saying their goodbyes, while others are gearing up for another round.

    One name that's likely to stick around is Tom Rothman. He's the head honcho at Sony Entertainment Pictures' Motion Picture Group. He's known for his lively speeches that get theater owners excited and laughing. Rothman is expected to keep his job, even though there's no official announcement yet. He'll kick off the show on Monday night, presenting Sony's upcoming movies.

    Meanwhile, Josh Greenstein, who shares the co-president title at Sony, might be eyeing a new gig. Rumors are flying that he could join Paramount if the Skydance-Paramount Global merger goes through. Greenstein has a history with Skydance's top brass, but nothing is set in stone yet. Sony, for now, says he's still part of their team.

    Over at Warner Bros. , things are a bit tense. Mike De Luca and Pam Abdy, the studio's movie bosses, are under the spotlight after a few box office flops. There are whispers that their boss, David Zaslav, is looking for replacements. Zaslav seems to be more interested in big-name franchises rather than films driven by individual directors. De Luca and Abdy, known for their professionalism, are bracing for potential changes.

    DC Studios co-heads Peter Safran and James Gunn will also take the stage. They'll be talking about upcoming titles like Superman. Safran, in particular, is rumored to be aiming for a bigger role at Warner Bros. beyond just DC. The release of Superman this July could be a big moment for him.

    Universal Pictures is keeping things steady, with Donna Langley continuing to expand her influence. She's now the chairman of NBCUniversal Entertainment and Studios, overseeing both film and TV. Things are a bit more dramatic at Amazon MGM Studios, where Jennifer Salke was recently let go. Mike Hopkins, the head of Prime Video and Amazon MGM Studios, is handing more power to Courtenay Valenti and Vernon Sanders.

    CinemaCon will be a big moment for Valenti, Sue Kroll, and Hopkins as Amazon MGM Studios makes a bold move into theaters, thanks to their recent acquisition of the James Bond franchise. Fans are eager for updates on the next Bond film and who will play the iconic role.

    Paramount is facing major changes, and Thursday's presentation might be Brian Robbins' last as Paramount Global co-CEO and CEO of Paramount Pictures. Robbins is known for his calm demeanor and has been a steady hand during uncertain times.

    Disney wraps up the show on Thursday afternoon. Alan Bergman, who oversees Disney's massive film empire, is expected to take the stage. Despite a recent flop with Snow White, Disney has plenty to celebrate, including finishing No. 1 in market share for most of the past nine years. Bergman has kept the company's seven film divisions on track, including replacing the head of live-action movies after the Snow White misstep. There will be a big change at Lucasfilm by next year's CinemaCon, with rumors of Kathleen Kennedy stepping down after a decade in charge.

    The event will close with a bang, featuring the next installment of Avatar, directed by James Cameron. This highly anticipated film is sure to impress theater owners and overshadow any executive drama.
