It was the other Oscars stuff-up.
While minor compared to getting the winner of best picture wrong, the Academy Awards made an unhappy error during the emotional 'In Memoriam' segment.

Oscars mix-up: La La Land producer, Emma Stone react
The 87th Academy Awards end with a major bungle as La La Land is wrongly announced as winning best picture instead of Moonlight. Vision courtesy A.M.P.A.S.
Among such beloved well-known names in the tribute as Carrie Fisher, Gene Wilder and Prince was Australian designer Janet Patterson, who died late last year.
She was a four-time Oscar nominee for The Piano, The Portait of a Lady, Oscar and Lucinda and Bright Star.
But instead of Patterson, who always sought privacy during her distinguished career, the awards featured a picture of her longtime collaborator and friend Jan Chapman.
As producer, Chapman worked with Patterson and director Jane Campion on such films as 2 Friends, The Piano, Holy Smoke and Bright Star.
The mistake upset both Chapman and Patterson's many friends in Australian film and television.

"I was devastated by the use of my image in place of my great friend and long-time collaborator Janet Patterson," Chapman said in an email to Variety.
"I had urged her agency to check any photograph which might be used and understand that they were told that the Academy had it covered. Janet was a great beauty and four-time Oscar nominee and it is very disappointing that the error was not picked up."

The photograph used at the Oscars appears to be a wrongly captioned Getty Images picture taken in 2010.
When Patterson passed away, the agency that represented her in the United States reflected her desire for privacy when it simply said she died in Australia but due to the wishes of her family gave no details of her age or the date of her death.
While her work was exceptional, Patterson preferred to avoid interviews and awards ceremonies.
When she was Australia's best hope at the Oscars for Bright Star in 2010, she told The Age she was not sure she would even attend the awards.
"I'm actually studying and I've got a busy life, so we'll see how things go with my family and the bigger picture" she said. "I don't care about that [winning]."
When she declined interviews and released no images of herself, Chapman described her as "a hidden treasure of the Australian film world".
Patterson's last film was designing costumes for Far from the Madding Crowd (2015).
In a obituary in The Sydney Morning Herald, Chapman and Campion described her as "our brilliant friend; kind, impish, fiercely intelligent, beautiful."
It continued: "Janet was private and discreet yet deeply heartful, generous and engaged with life. Even while ill, fighting cancer she was strong, positive, determined."
