Looking back at the most shocking Oscar moments, from ‘La La Land’ flub to John Travolta mispronouncing Idina Menzel’s name

It wouldn’t be an Oscars ceremony without a plot twist or two along the way.

From unusual moments to uncomfortable performances to unexpected winners, Hollywood’s biggest night doesn’t always go according to script.

Ahead of this Sunday’s 93rd Academy Awards, here are some of the most jaw-dropping moments in Oscars history.

The 2017 best picture flub

Perhaps no moment at any awards show has been as shocking as Warren Beatty and Faye Dunaway announcing the wrong winner for best picture four years ago.

For several minutes, the world thought Ryan Gosling and Emma Stone’s fantastical musical “La La Land” won the awards show’s top honor — until a producer on the film, Jordan Horowitz, revealed a mistake was made.

“This is not a joke,” Horowitz said.

The coming-of-age drama “Moonlight” was then crowned the winner — after the makers and stars of “La La Land” had already begun celebrating on stage. Awkward.

Rob Lowe’s opening number with Snow White

The 1989 Oscars hit a low note when Rob Lowe performed a bizarre musical number alongside an actress dressed as Snow White.

That ceremony didn’t feature a traditional host and instead turned to Lowe — not exactly known as a song-and-dance man — and his rendition of “Proud Mary” to open the show.

However, the 11-minute performance was widely panned — and the Oscars went another 30 years before it operated without a host again.

John Travolta mispronounces Idina Menzel’s name

Viewers just couldn’t let it go in 2014 when Travolta introduced Menzel as “Adele Dazeem.”

Menzel was a star both on the stage and the screen, having originated roles in “Rent” and “Wicked” on Broadway, and voicing Princess Elsa in “Frozen.”

Menzel got the last laugh at the next Oscars when she introduced Travolta as “Glom Gazingo.” That segment saw Travolta creepily caress Menzel’s face and call her his “darling” and “wickedly talented Idina Menzel.” A rep for the “Pulp Fiction” actor later said the moment was rehearsed.

Streaker at the Oscars

The naked truth about the 1974 Oscars is that a nude streaker who stunningly ran onstage ended up upstaging a theater full of Hollywood icons.

The ceremony’s host, David Niven, was introducing Elizabeth Taylor when the streaker appeared behind him, flashed a peace sign and scurried away.

“Isn’t it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings?” Niven quipped.

Alfred Hitchcock’s short speech

The Master of Suspense, who had been directing since the silent film era, didn’t have much to say during his acceptance speech for the honorary Irving G. Thalberg Memorial Award in 1968.

He simply said, “Thank you,” before stepping back and adding, “very much indeed.”

It marked the first and only Oscar of Hitchcock’s prolific career, and came nearly three decades after his first nomination.

Adrien Brody kisses Halle Berry

In 2003, Brody walked onstage after winning best actor for “The Pianist” and spontaneously planted an old-fashioned, Hollywood-style movie kiss on Berry, who presented the award.

Berry, who good-naturedly went along with the stunt, later confirmed the kiss — which would never fly in todays #MeToo world — wasn’t planned.

“I was like, ‘What the f—k is happening right now?’ " Berry recalled during a 2017 appearance on “Watch What Happens Live.”

She continued, “That is what was going through my mind. Because I was there the year before, and I know the feeling of being out of your body, I just f—king went with it. But I was like, ‘What the f—k is going on right now?’ ”

“Shakespeare in Love” wins best picture

Arguably the biggest upset best picture winner in Oscars history was the lighthearted romantic drama “Shakespeare in Love,” which emerged victorious in a 1999 field that included sprawling World War II epics “Saving Private Ryan” by Steven Spielberg and Terrence Mallick’s “The Thin Red Line.”

Gwyneth Paltrow’s win for best actress for “Shakespeare in Love” was also considered a surprise. She beat Fernanda Montenegro, who starred in the Brazilian-French drama “Central Station,” and Cate Blanchett, who portrayed Queen Elizabeth I in “Elizabeth.”

Marlon Brando doesn’t accept award

Brando didn’t take the stage when he was named best actor for the mobster classic “The Godfather” in 1973.

Instead, a Native American activist took the stage and said Brando would not be accepting the “very generous award” due to the “treatment of American Indians today by the film industry, and on television, in movie reruns and also with recent happenings at Wounded Knee.”

The audience reaction to Sacheen Littlefeather as she gave the speech on Brando’s behalf was split among cheers and jeers.

Jack Palance does pushups

The septuagenarian actor got hearts pumping when he memorably dropped to the ground and started doing one-armed pushups after winning best supporting actor in 1992 for the Western comedy “City Slickers.”

“When you reach a certain age plateau, the producers ... talk about you and they say, ‘Can we risk it?’”

The actor, who was 73, then showed his youthful form by doing the pushups on stage, earning a huge round of applause.

The 2021 Oscars take place Sunday at 8 p.m. EDT on ABC.

The awards show will be held at two locations in Los Angeles amid the COVID-19 pandemic: the standard Dolby Theatre, and the nearby Union Station.
