UPDATE: The Academy has fixed their mistake in the In Memoriam section on their website and released a statement regarding the unfortunate snafu.
"We sincerely apologize to producer Jan Chapman, whose photo was mistakenly used in the Oscars In Memoriam tribute for her colleague and dear friend, the late Janet Patterson," the statement explained early Wednesday.
"Janet, an Academy member and four-time Oscar-nominated costume designer, was beloved in our community. We extend our deepest apologies and condolences to the Patterson family."
Australian producer Jan Chapman was "devastated" when she saw her face on screen during the 2017 Oscars In Memoriam segment.
Janet Patterson, an Australian costume designer and four-time nominee, passed away in October 2015, but instead of using a photo of her, The Academy accidentally used a picture of her friend Chapman, who is still alive.
"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," she told Variety. "Janet was a great beauty and four-time Oscar nominee and it is very disappointing that the error was not picked up. I am alive and well and an active producer."
Patterson and Chapman worked together on The Piano.
