A number of prominent performers who died within the past year were notably excluded from the “In Memoriam” segment of the Oscars last Sunday.

TV “Batman” Adam West, singer and actress Della Reese and longtime musician and TV host Glen Campbell were among the stars who were not mentioned during the emotional segment.

David Cassidy, who starred on “The Partridge Family,” and John Mahoney of “Frasier” were also left out, as were Robert Guillaume, “Goodfellas” and “The Sopranos” star Frank Vincent, “Animal House” actor Stephen Furst and “Dick Van Dyke Show” actress and longtime entertainer Rose Marie.

Former best supporting actress recipient Dorothy Malone was also excluded. She won that coveted honor in 1956 for her performance in “Written in the Wind.”

Directors Tobe Hooper (“Texas Chainsaw Massacre” and “Poltergeist”) and Lewis Gilbert, who received an Oscar nomination for “Alfie” in 1967, also did not appear.

The annual “In Memoriam” segment featured tributes to a bevy of stars who died since last year’s show, such as Glenne Headly, James Bond actor Roger Moore and actress and director Jeanne Moreau.

Pearl Jam lead singer Eddie Vedder provided the music for the segment with a live rendition of “Room at the Top” by late rock icon Tom Petty.

The omissions of West, who died last June at 88, and others were quickly criticized on social media by fans.

“That was a beautiful tribute to some incredible artists, but where was Adam West?! That man gave so much to the world of film, TV, pop culture and comic books,” wrote Twitter user Michael Patterson.

TV One host Roland Martin tweeted, “Hey TheAcademy! How did you forget Robert Guillaume and Della Reese in your In Memoriam? They were both in movies!”

Guillaume died in October at 89, and Reese died the following month at 86.

Mahoney — who portrayed the beloved father of the titular character on “Frasier” but also appeared in films — died four weeks before the Oscars at 77.

Campbell, who died in August at 81, was widely known for his television and music work but was nominated for the best original song Oscar just three years ago for “I’m Not Gonna Miss You,” which appeared in his documentary “Glen Campbell: I’ll Be Me.”
