Other noteworthy stars left off the list included Cameron Boyce, who tragically died in July at the age of 20, and horror film legend Sid Haig.
On Monday morning, the Academy released a statement explaining their decision.
"The Academy receives hundreds of requests to include loved ones and industry colleagues in the Oscars In Memoriam segment," the statement read.
"An executive committee representing every branch considers the list and makes selections for the telecast based on limited available time. All the submissions are included on Oscar.com and will remain on the site throughout the year. Luke Perry and Cameron Boyce are remembered in the Oscar.com gallery."
