Bill Murray gave fans something to buzz about this week: a surprise reunion with Wes Anderson in Paris, where the pair teased a long-rumored Western that could reunite Murray with Owen and Luke Wilson. Nothing’s confirmed yet, but it’s a good excuse to revisit a question that never quite gets settled: what’s actually Murray’s best comedic performance? Ghostbusters and Groundhog Day get all the credit, but tucked between those touchstones sits a film that rarely enters the conversation.
Though he has been seen more as a dramatic actor as of late, Bill Murray is undoubtedly the man that redefined comedy during the ’70s and ’80s. His filmography includes comedy classic after comedy classic, including some of the most critically successful movies of the 20th century.
From Ghostbusters to Groundhog Day, Murray was making an entire generation laugh with his deadpan comedy and impeccable comedic timing. However, between those movies lies one of his finest films, and it’s one that doesn’t receive the recognition it deserves.
1991’s What About Bob? might be Bill Murray’s most solid comedic performance. The chemistry between him and his co-star, Richard Dreyfuss was as tense in front of the camera as it was behind it, and maybe that’s why the pair works so well here.
What Is What About Bob? About?

In What About Bob? Murray plays the titular Bob: a conflicted man who suffers from every type of phobia under the sun. He crashes the vacation of his psychiatrist, Dr. Leo Marvin (played by Dreyfuss), causing him to lose his composure at every step of the way.
While Marvin absolutely despises Bob, his family loves him despite his many flaws. In fact, they show more love for Bob than they do for him, which infuriates him even more. This love/hate relationship between Bob and Marvin is what makes the movie so special, as Bob might be one of Murray’s most innocent characters.
In the end, however, Marvin learns to tolerate Bob, a story that wasn’t as touching in real life.
Bill Murray and Richard Dreyfuss Really Did Hate Each Other

It’s no secret that Dreyfuss and Murray pretty much hated each other during the filming of What About Bob? Even the movie’s director, Frank Oz, has gone on record saying how stressful the whole situation was.
The result, however, is one of the best comedies of the ’90s. Despite the hostility, the fact that Dreyfuss and Murray didn’t see eye to eye helped them with their characters’ chemistry. There are some scenes where you can almost feel how Marvin truly despises Bob, and that might be because Dreyfuss loathed having to work with Murray.
While there are a lot of different explanations for their feud, Dreyfuss recalls a particular incident that sparked their hatred. He says that a drunken Murray threw an ashtray at him, nearly missing him. This physical assault was the straw that broke the camel’s back for their relationship and decided how they would see each other until this day.
[EDITOR’S NOTE — There’s a documented account from Rolling Stone’s 2025 oral history, where Frank Oz describes Murray heaving a glass against a fireplace during a script dispute, not at Dreyfuss directly.]

Robin Williams Was Almost Cast as Bob Wiley

One of the reasons why Bill Murray works so well for Bob’s role is that he simply looks like a guy who could do no wrong. There’s a certain innocence in Murray’s eyes that’s hard to describe, and that’s why the unbelievably obnoxious Bob still comes across as charming during most of the film.
Though it seems like Bob was tailor-made for Bill Murray, he wasn’t the studio’s first choice to play the character. That distinction goes to everyone’s favourite lovable comedian, Robin Williams.
Additionally, Steve Martin was also considered for both Bob and Leo Marvin. It’s hard to imagine What About Bob? without Murray’s creativity, especially because he improvised many of the film’s funniest moments.
The casting history goes even deeper: Woody Allen was approached to play Dr. Marvin — and possibly co-write the script — while Patrick Stewart was also floated for the role, and Garry Marshall was briefly attached to direct before Frank Oz came aboard.
It’s not that Bob was made especially for Murray that made him so special, it’s that Murray reconstructed the character using his own comedic genius.
Maybe Robin Williams could have played a charming version of the character, but it’s safe to say that no other actor could have done it in the same iconic way as Bill Murray did.
How Did Critics and Audiences Rate It?
What About Bob? holds a 71% on Rotten Tomatoes from 124 critics and a 60/100 on Metacritic — solidly good, if not universally beloved. It grossed $63.7 million against a $39 million budget, making it the 15th highest-grossing film of 1991. Roger Ebert gave it a thumbs up, calling it Murray’s best film since Ghostbusters; his Siskel & Ebert co-host Gene Siskel gave it a thumbs down, put off by Dreyfuss’s arrogance in the role. That split is arguably the film’s whole appeal — Marvin is supposed to be insufferable.
