Are Bill Murray and Brian Doyle-Murray brothers?

Yes, they are brothers, and Brian is the older of the two. According to Rotten Tomatoes, Brian Doyle-Murray is “the older brother of actor Bill Murray.” The pair have appeared together in several films, including Caddyshack and Groundhog Day, both of which Brian co-wrote or appeared in.

Brian originally used the surname Murray but added “Doyle” to avoid confusion with another actor named Brian Murray, as Apple TV notes. He is also the brother of actor Joel Murray, according to the Ghostbusters Wiki.

Bottom line: Brian Doyle-Murray is the older brother of Bill Murray. The two share the screen in Caddyshack and Groundhog Day, but Brian’s career extends well beyond those collaborations.

Why this matters

The “brother of” label sometimes overshadows Brian’s own writing and acting credits. But the pattern is clear: without Brian paving the way at Second City, Bill may never have entered comedy.

The implication: Brian’s role as a trailblazer in the family is often overlooked.

Is Brian Doyle-Murray Irish?

Brian Doyle-Murray was born in Chicago, Illinois, and is an American citizen. His father was of Irish descent, but he himself is American by nationality. He has occasionally portrayed Irish characters on screen, though his personal background remains rooted in the U.S. Midwest.

The Apple TV biography notes he attended Loyola Academy, a Jesuit school in Illinois, before moving on to St. Mary’s College of California. No official record links him to Irish citizenship.

The catch

While Doyle-Murray has benefited from an Irish‑American cultural identity in some roles, his career trajectory is purely Chicago‑born. The Irish connection is ancestral, not professional.

The catch: despite his Irish surname, his career is firmly American.

What is Brian Doyle-Murray most famous for?

Doyle-Murray’s best‑known acting role is arguably the groundhog (Buster) in the 1993 comedy Groundhog Day, as confirmed by Rotten Tomatoes. He also co‑wrote the screenplay for Caddyshack (1980) alongside Harold Ramis and Doug Kenney, a film that became a cultural touchstone.

He played Jack Ruby in Oliver Stone’s JFK (1991) and has appeared in National Lampoon’s Vacation (1983), Scrooged (1988), Ghostbusters II (1989), and Multiplicity (1996) – all documented by Rotten Tomatoes.

Notable film roles

  • Caddyshack (1980) – co‑writer and actor
  • National Lampoon’s Vacation (1983) – role as the camping‑ground attendant
  • JFK (1991) – Jack Ruby
  • Groundhog Day (1993) – Buster the groundhog

Voice work

Beginning in the early 2000s, Doyle‑Murray provided the voice of the Flying Dutchman in the animated series SpongeBob SquarePants – a role that introduced him to a new generation of viewers. The character appeared in multiple episodes and a video game.

Writing credits

Beyond Caddyshack, he honed his writing talents on SCTV and Saturday Night Live during the late 1970s and early 1980s, according to Rotten Tomatoes.

Bottom line: Doyle-Murray is most famous for writing Caddyshack and playing the groundhog in Groundhog Day. But his filmography spans decades and genres, proving he is more than a one‑role performer.

This breadth of work cements his legacy beyond the shadow of his brother.

Is Brian Doyle-Murray still alive?

Yes, Brian Doyle-Murray is alive as of 2025. He celebrated his 80th birthday on October 31, 2025. Although he has been less active on screen in recent years, he continues to take occasional voice roles and public appearances. The Rotten Tomatoes bio lists his years active as “1970s–present,” confirming his ongoing involvement in the industry.

Fans can still catch his work in reruns of SpongeBob SquarePants and streaming platforms that carry his classic films.

The pattern: he remains active in the industry despite a lower public profile.

How old is Brian Doyle-Murray?

Brian Doyle-Murray was born on October 31, 1945 in Chicago, Illinois, making him 80 years old as of 2025. His birth date is verified by Rotten Tomatoes and Apple TV. He was the first of the Murray siblings to enter show business, reportedly joining The Second City in the early 1970s.
