The 89th Academy Awards honored fallen stars like Carrie Fisher, Debbie Reynolds, and Gene Wilder in Sunday's "In Memoriam" segment, but left out one classic, Philly-born actor: Jon Polito.

Polito, 65, died in a hospital in Duarte, Calif., in September following a battle with multiple myeloma. He was survived by partner Darryl Armbruster, according to the Associated Press.

Born and raised in Philadelphia, Polito graduated from Villanova University with a degree in theater. According to the New York Times, the actor began his career on Broadway with roles in The Curse of an Aching Heart and Death of a Salesman in 1982 and 1984.

From there, Polito began his work on television and in movies, appearing in projects like Homicide: Life on the Street and Flags of Our Fathers. He later became known for his work in Coen Brothers films like Miller's Crossing, Barton Fink, and The Big Lebowski.

Polito's absence from the "In Memoriam" segment did not go unnoticed on social media:

In addition to Polito, the segment also failed to include fallen celebs like Alan Thicke, Florence Henderson, and Robert Vaughn, all of whom passed away in 2016. In previous years, the Oscars ceremony has left off other stars from the annual segment, including 2015's snub of Joan Rivers, who passed away in 2014.

This year's segment also featured another major flub with a tribute to Janet Patterson, a four-time Oscar nominated costume designer who died in October. The segment showed Patterson's name alongside a photo of producer Jan Chapman, who is still alive.

The error was on top of the now-notorious La La Land/Moonlight debacle in which presenter Faye Dunaway announced La La Land as the 2017 Best Picture winner, when Moonlight was the actual award recipient.
