O'Neal joined a growing chorus of Hollywood actors including Jane Fonda and Roger Ebert to express his dismay at the former Charlie's Angels actress's snub from the ceremony.
"There is no comment other than we were disappointed that she was not included," O'Neal's spokesperson told People.
Fonda and Ebert both took to their Twitter accounts to reveal their displeasure during the event. "No Farrah Fawcett in the memorial tribute? Major fail," Ebert wrote.
"And where was Farrah Fawcett? She should have been included #oscars #FAIL," posted Fonda later.
However, Academy spokeswoman Leslie Unger earlier insisted that the segment can only contain so many people each year. "Every year it's an unfortunate reality that we can't include everybody," she explained.
Last week, Academy executive director Bruce Davis spoke about the difficulty the organisers face when putting the montage together, telling The AP: "It is the single most troubling element of the Oscar show every year... Because more people die each year than can possibly be included in that segment."
