This year's Academy Awards was not an entirely smooth affair, given that massive Best Picture screw-up.
But it turns out there was another massive error, even worse than the La La Land/Moonlight gaffe - the 'In Memoriam' section honouring those who have passed away in the last year showed someone who is still alive.
Australian film producer Jan Chapman said she was "devastated" after her picture was used to show the late Janet Patterson, a costume designer who passed away in October 2015 and had worked on movies such as The Piano and Bright Star.
While Patterson's name and occupation were correct in the montage tribute to her, the picture was most definitely not.
"I was devastated by the use of my image in place of my great friend and long-time collaborator Janet Patterson," Chapman told Variety of the error.
"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. I am alive and well and an active producer."
Chapman has been involved in movies such as Lantana and Holy Smoke, and she had actually worked with Patterson on The Piano.
The In Memoriam segment, which was accompanied by singer Sara Bareilles, also honoured stars such as Carrie Fisher, Debbie Reynolds and Gene Wilder.
The main talk of the night has been the Best Picture mix-up, in which La La Land was mistakenly announced instead of actual winner Moonlight.
