The Oscars 2018 ceremony managed to make it through without any major mishaps, but some great Hollywood actors and creatives who passed away last year were unfortunately left out of this year's "In Memoriam" montage. Pearl Jam frontman Eddie Vedder performed a cover version of Tom Petty's "Room at the Top," while the Academy remembered some of the recently departed greats - including director George A. Romero, James Bond actor Roger Moore, and composer Jóhann Jóhannsson, who passed away just a few weeks ago. But here are a few people who didn't make it into the montage.

Tobe Hooper, director of one of the most iconic horror movies of all time, The Texas Chainsaw Massacre, passed away at the age of 74 in August 2017. Hooper's omission from the "In Memoriam" segment has attracted perhaps the biggest outcry from fans, given how influential Texas Chainsaw Massacre has been within the genre since its release more than forty years ago, as well as Hooper's contributions to horror since then (including the 1982 classic Poltergeist). The omission was particularly egregious since a clip from Texas Chainsaw Massacre was actually featured in another Oscars montage this year.

John Mahoney, who played Martin Crane for 11 years on Frasier and also starred in movies like Primal Fear, The Hudsucker Proxy and Say Anything, passed away on February 4th, 2018, at the age of 77, due to complications from throat cancer.

Adam West, the beloved actor who played Batman in the 1960s TV series, passed away in June 2017 at the age of 88. Though he was best known for his TV work (including, in recent years, voicing Mayor Adam West in Family Guy), he also appeared in many movies, including the 1966 Batman movie.

Powers Boothe, who played HYDRA leader Gideon Malick in The Avengers and Agents of SHIELD, died in May 2017 at the age of 68. He also played Senator Roark in Sin City and Sin City: A Dame to Kill For, and his other movie credits include Red Dawn, Frailty and Oliver Stone's Nixon.

Rose Marie, who was best known for her role as Sally Rogers in The Dick Van Dyke Show, died in December 2017 at the age of 94. She began her career as a child performer and singer called Baby Rose Marie, and ultimately ended up working in the entertainment business for the better part of a century.

Robert Guillaume, the voice of Rafiki in The Lion King, passed away due to prostate cancer in October, 2017, at the age of 89.

Of course, the film industry loses a lot of people every year, and it's not always possible to include everyone in the 'In Memoriam' montage. If there's another Hollywood great that passed away last year, whom you felt was overlooked by the Oscars, let us know in the comments!
