Two other mistakes that happened at the Oscars

Los Angeles — Actress Patricia Arquette says she was upset the Oscars left her transgender sister out of the "In Memoriam" tribute.

Arquette told ABC News she thought the Academy Awards "would have a little bit more respect" for the transgender community. Arquette says her sister Alexis Arquette should have been honoured because she had a great body of work and was one of few transgender artists in the business.

Alexis Arquette died on 11 September from a heart attack and battled HIV for 29 years.

She memorably played a trans sex worker in Last Exit to Brooklyn and a Boy George impersonator in The Wedding Singer.

The "In Memoriam" portion of the show remembers major Hollywood film figures who died last year. This year's segment included Debbie Reynolds, Carrie Fisher and Gene Wilder.

Others left out included Florence Henderson and Garry Shandling. 

Wrong photo shown

Janet Patterson, an Australian costume designer who died in October, was shown not with her picture but with that of the well-known Australian producer Jan Chapman.

"I was devastated by the use of my image in place of my great friend and longtime collaborator Janet Patterson," Chapman told industry publication 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," she added.

"I am alive and well and an active producer."

Patterson and Chapman worked together on the 1993 film The Piano, which won three Academy Awards. Chapman is also known for The Last Days of Chez Nous (1992).
