It’s an unfortunate, yet seemingly inevitable, Oscars occurrence: Every year, without fail, someone is left out of the “In Memoriam” sequence.

This year’s offensive exclusion appears to be the late, great Joan Rivers, whose absence from the montage sent the Twitterverse into an immediate tizzy — and rightfully so.

For the record, Rivers appeared in many films during her incredible career in Hollywood, including Muppets Take Manhattan (pictured), Serial Mom, Iron Man 3, Spaceballs, The Smurfs and her own documentary A Piece of Work. She also directed the 1978 comedy Rabbit Test, which starred Billy Crystal and Doris Roberts. (And let’s not forget that Rivers is largely responsible for putting the Oscars’ red carpet on the map.)

The Emmy-winning comedian died in Sept. 2014, following surgery complications.

UPDATE (Feb. 23): The Academy of Motion Picture Arts and Sciences has released a statement regarding the omission…

Joan Rivers is among the many worthy artists and filmmakers we were unfortunately unable to feature in the In Memoriam segment of this year’s Oscar show. She is, however, included in our In Memoriam gallery on Oscar.com.
