The Ghost in the Invisible Bikini

The Ghost in the Invisible Bikini is an American comedy horror beach film from 1966, directed by Don Weis and starring Tommy Kirk, Deborah Walley, Aron Kincaid, Quinn O'Hara, and other notable actors. It's the last of seven beach party films produced by American International Pictures. The film separates itself from others in the series, by introducing elements of the supernatural, creating a unique blend of the beach and horror-fantasy genres.

The primary protagonist, set in a distinctly 60s-pop milieu, is Chuck Phillips, engagingly played by Tommy Kirk. He leads a “rat pack” of multifaceted teenagers who hold an impromptu party, complete with rock ‘n’ roll music and energetic dance numbers, at a stately mansion. However, the mansion isn't as ordinary as it seems. A recently deceased wealthy man, Hiram Stokely (Boris Karloff), who resides there alongside his long-deceased lover, Cecily (Susan Hart), gives it a mysterious aura. Cecily, now a ghost in the titular "invisible bikini", adds an intriguing layer of the supernatural to this beach horror-comedy.

The plot is set into motion when Hiram is given a chance to enter heaven by performing one good deed within 24 hours. He must ensure his legal heir gets the prized inheritance left behind, despite the machinations of a crafty lawyer and his henchmen looking to unlawfully secure the inheritance for themselves. The story unfolds in a series of comic mishaps, confusions, and delightful teenage antics, adorned with colorful 60s fashion, iconic dance sequences, and adventurous explorations into the supernatural.

Tommy Kirk showcases a charming performance as Chuck while Deborah Walley shines as the lively and loveable teenager, Sinistra, who manages to attract the attraction of numerous male guests at the party. Their romantic subplot brings a fresh and engaging dynamic that enhances the central plot. Aron Kincaid also deserves a mention in his comical role as the strong but none-too-bright henchman, Chicken Feather.

The Ghost in the Invisible Bikini features a strong supporting cast, including notable appearances from Boris Karloff as the comically foreboding Hiram and Basil Rathbone as Reginald Ripper, the deceitful lawyer. Additionally, the ethereal Susan Hart impresses with her charismatic and playful portrayal of the ghostly Cecily.

The film also features musical numbers performed by popular bands and artists of the period, such as Nancy Sinatra and The Bobby Fuller Four, enriching the overall surreal-psychedelic ambience that is so characteristic of the 60s. The hauntingly catchy title song, “Geronimo”, is a musical highlight that perfectly evokes the film’s unique blend of genres.

The film's unique amalgam of beach party shenanigans, spooky-house elements, slapstick comedy, and musical interludes, set against a supernatural backdrop, offers an engaging viewing experience. The vibrant and colorful visuals encapsulate the essence of classic 60s cinema, capturing the youthful optimism and adventurous spirit of the era. This film might not have achieved the cult status of some of the other entries in the series, but the novelty of the invisible bikini and the ghostly romantic subplot make it memorable in its own right.

The Ghost in the Invisible Bikini functions as an innocent, fun-filled trip down memory lane, an entertaining exhibit of the bygone era’s blend of horror, comedy, music, and beach-party tropes. Its unique juxtaposition of seemingly disparate elements, coupled with its catchy musical numbers, engaging performances, and clever comedic elements, makes it an enjoyable watch. Although the film is firmly rooted in its era, it still possesses a timeless charm with its endearing characters, lively humor, and unique approach to combining genres. It's not just a film, but a nostalgic slice of pop culture from the swinging sixties.
