The Academy attempted to pay tribute to Janet Patterson
La La Land being mistakenly announced as the winner of the best picture award was not the only slip up at the Oscars this year.
During the show's ‘In Memoriam’ tribute to industry figures who have passed away in the last 12 months, a photograph of a woman who is still alive was used by mistake.
The mishap came as the Academy attempted to pay tribute to Janet Patterson.
Instead of showing a picture of the costume-designer, an image of fellow Australian Jan Chapman was shown alongside Patterson's name and job description.
Patterson, who died in October, was a four-time Oscars nominee for films The Piano, Portrait of a Lady, Oscar and Lucinda, and Bright Star.
Jan Chapman meanwhile is one of Australia's leading film-makers.
She had previously worked with Patterson on Bright Star and The Piano.
In a statement to Variety, Chapman said: "I was devastated by the use of my image in place of my great friend and long-time collaborator Janet Patterson.
"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 ‘In Memoriam’ video paid tribute to stars including Carrie Fisher, Prince and Debbie Reynolds – however it omitted actor Bill Paxton, who died on Sunday.
It played during a rendition of the Joni Mitchell song Both Sides Now by Sara Bareilles.
