How Gilligan’s Island and Gunsmoke Shared the Same CBS Studio Lagoon Set

Television history often obscures the practical realities of studio production, where disparate genres frequently occupy identical physical spaces. During the 1960s and beyond, CBS Studio Center housed one of Hollywood’s most versatile water locations—a man-made lagoon that served as both a tropical shipwreck site and a Kansas watering hole. This unlikely production marriage connected Sherwood Schwartz’s three-season sitcom “Gilligan’s Island” with the two-decade Western epic “Gunsmoke,” allowing both series to capture essential waterfront scenes without departing the Studio City backlot.

Building the Backlot’s Aquatic Center

Construction of the lagoon set in 1964 marked a strategic operational shift for “Gilligan’s Island” production logistics. After filming the series’ first two episodes on location at Malibu and Zuma beaches, producers determined that transporting cast and crew to coastal locations proved logistically cumbersome and financially inefficient for an ongoing series. CBS responded by excavating a substantial water feature at their Studio Center facility, creating a controlled environment where the S.S. Minnow castaways could interact with water, receive visitors, and discover washed-up objects central to weekly episode plots.

The location presented unique environmental challenges that impacted shooting schedules. Situated adjacent to the Ventura Freeway, the set forced production teams to accommodate morning rush hour traffic patterns. Crews regularly delayed filming until commuter congestion subsided, ensuring that automotive noise would not infiltrate audio recordings intended to depict remote tropical wilderness. Despite these acoustic complications, the lagoon became integral to CBS’s television manufacturing infrastructure, occupying significant real estate on the Studio City backlot while enabling storylines that required water access.

Western Repurposing and Visual Transformation

The same water that supported Gilligan’s tropical adventures periodically represented Dodge City’s outskirts when “Gunsmoke” required aqueous locations for Kansas-based narratives. Production designers implemented rapid environmental transformations, stripping the lagoon of its palm fronds and bamboo accents before replacing tropical vegetation with sagebrush and tumbleweeds. Mary Ann actress Dawn Wells recalled these metamorphoses in interviews with the Los Angeles Times, describing how cast members would arrive on stage to discover an entirely transformed landscape depending on which production held shooting priority that week.

This geographical flexibility extended beyond mere background dressing into narrative integration. The first season “Gilligan’s Island” episode “The Sound of Quacking” explicitly utilized this production connection, featuring a dream sequence where castaways found themselves transported to Dodge City. Two established “Gunsmoke” locations made surreptitious appearances during this installment, effectively placing the stranded islanders within the Western’s established geography. The practice highlighted CBS’s resource-maximization strategy, where expensive physical assets demanded utilization across multiple productions to justify their construction and maintenance costs.

The Lagoon’s Extended Television Family

Beyond its most famous occupants, the CBS lagoon supported an impressive roster of productions spanning multiple decades and genres. The water feature functioned as a reusable asset for various network properties requiring aquatic backdrops without the expense of location shooting:

• The Big Valley: Incorporated the set for Western water sequences involving the Barkley family ranch
• The Wild Wild West: Utilized the location for frontier-era spy adventures requiring river or lake settings
• St. Elsewhere: Later repurposed the aging structure for medical drama storylines in the 1980s
• Evening Shade: Featured the location during its early 1990s production run
• Gunsmoke: Regularly transformed the tropical paradise into Kansas terrain for Marshal Matt Dillon’s adventures
• Gilligan’s Island: Served as the primary tenant and most frequent user from 1964 through 1967

This collective utilization demonstrated mid-century television’s communal approach to physical production, where infrastructure investments demanded maximum return across diverse programming slates ranging from sitcoms to medical dramas.

Resource Competition and Network Strategy

The shared physical space mirrored broader corporate relationships between the productions under CBS president William S. Paley’s leadership. While “Gunsmoke” accumulated twenty seasons of Western narratives, “Gilligan’s Island” concluded after three years—a cancellation reportedly executed by Paley specifically to expand “Gunsmoke” programming slots and allocate additional resources to the higher-rated Western.

Actor Kurt Russell notably bridged these worlds early in his career, appearing in both productions during his formative Hollywood years. This casting crossover represented the tight-knit nature of CBS’s production community, where soundstages and backlot facilities fostered informal connections between seemingly unrelated projects sharing the same corporate umbrella and physical resources.

Demolition and Legacy

The lagoon’s utility persisted until the mid-1990s, when evolving studio infrastructure demands finally superseded the aging water feature. CBS paved over the location to create additional parking facilities, eliminating one of television’s most hardworking aquatic sets after three decades of continuous service. The transformation from production centerpiece to asphalt parking paralleled broader shifts in studio operations, as backlot filming gradually yielded to location shooting and emerging digital production alternatives.

Today, the shared history of these productions serves as a reminder of television’s industrial pragmatism. What appeared to audiences as distinct geographical locations—a remote Pacific island and a Kansas frontier town—actually occupied identical coordinates in Studio City, separated only by temporary vegetation, production design ingenuity, and the imagination of art directors who could transform paradise into the prairie within hours.
