While presenting awards, Sigourney Weaver and Pedro Pascal -- stars of this year's "Star Wars" film "The Mandalorian & Grogu" -- performed a bit that featured Grogu (also known as Baby Yoda) in the audience.
And Vogue doyenne Anna Wintour alongside Oscar winner Anne Hathaway delivered a humorous sketch that doubled as promo for the forthcoming "The Devil Wears Prada 2," to be released this spring.
Marvel cinematic universe stars Chris Evans and Robert Downey Jr. also reunited onstage ahead of the release of "Avengers: Doomsday" later this year.
CONAN'S JOKES
Host Conan O'Brien nodded to politics and pulled a few punches, some with global appeal and a few one-liners for the insiders.
"It's great to be back hosting the Oscars. Last year, when I hosted, Los Angeles was on fire. But this year, everything's going great," he joked, pausing for effect.
O'Brien also had a pointed industry remark for Netflix CEO Ted Sarandos: "It's his first time in a theater."
He also alluded to the Jeffrey Epstein drama.
"It's the first time since 2012 that there are no British actors nominated for best actor or best actress," O'Brien said. "A British spokesperson said, 'Yeah, well, at least we arrest our pedophiles."
"Marty Supreme" star Timothee Chalamet, who left empty-handed, also got a notable roast, as O'Brien took shots at the actor who recently disparaged ballet and opera.
