1980s The first film MacLachlan worked on was
The Changeling (1980), part of which was shot on the University of Washington campus. He was paid $10 as an
extra. MacLachlan made his film debut in
Dune (1984) in the starring role of
Paul Atreides. MacLachlan was performing in
Molière's
Tartuffe at a Seattle-area theater when a
casting agent for
Dune producer
Dino De Laurentiis began searching for a young lead and received multiple recommendations for him. After several screen tests, he hit it off with director
David Lynch, aided by their common
Pacific Northwest backgrounds, and succeeded in winning the part. After
Dune flopped and met with poor reviews from critics, MacLachlan found it difficult to find work. He moved to
Los Angeles in 1985, and auditioned for several films, including
Top Gun, but failed to win any roles, eventually dropping his agent. Lynch biographer Chris Rodley described MacLachlan as an on-screen incarnation of Lynch's own persona. He starred in the 1987 science fiction action film
The Hidden as FBI agent Lloyd Gallagher. He also had a small role in the romantic comedy
Don't Tell Her It's Me.
1990s arriving at the

Twin Peaks (1990–91), playing
Special Agent Dale Cooper, reprising that role for Lynch's 1992 prequel film
Twin Peaks: Fire Walk with Me. Lynch commented on those roles in a
GQ story about MacLachlan: "Kyle plays innocents who are interested in the mysteries of life. He's the person you trust enough to go into a strange world with." Lynch, who was known to allow his collaborative partners a large degree of control over their roles when working with him, rewrote scenes in
Blue Velvet and
Twin Peaks at the request of MacLachlan, who felt they were not right for his characters. MacLachlan appeared as musician
Ray Manzarek in

Charlie Sheen. Also, in 1991, he played the role of a killer in

animated sitcom of the same name, portraying Cliff Vandercave, the movie's main antagonist, opposite
John Goodman as
Fred Flintstone and
Rick Moranis as
Barney Rubble. and it collected a record seven
Golden Raspberry Awards. MacLachlan recalls that when he watched
Showgirls for the first time before the premiere, he thought it was "horrible". But he later realised that the movie was "inadvertently funny" and embraced for its
campiness. According to MacLachlan, although he skipped the movie's
press tour, he had sat through the whole screening, contrary to reports that he walked out. In 2002, he made his
West End debut in
John Kolvenbach's
On an Average Day with
Woody Harrelson. In 2003, MacLachlan made his

Connie Britton in

Benito Skinner. The series premiered in May 2025 to positive reviews and was renewed for a second season in September 2025. In January 2025, the

The New York Times,
GQ and on his personal Instagram account, where he wrote, "I was willing to follow him anywhere because joining him on the journey of discovery, searching and finding together, was the whole point. I stepped out into the unknown because I knew David was floating out there with me. It's like Agent Cooper says to Sheriff Truman in
Twin Peaks: 'I have no idea where this will lead us, but I have a definite feeling it will be a place both wonderful and strange.' I will miss my dear friend. He has made my world—all of our worlds—both wonderful and strange". In September 2025, MacLachlan appeared once again alongside his
