Unlike Wisit's previous films, "The Unseeable" was written by Kongkiat Khomsiri, writer of "Art of the Devil 2". It was all too easy for me to imagine what "The Unseeable" might have looked like had a director with lesser artistic aspirations been given the script. As it is, "The Unseeable" has the formal excellence of Wisit's first two films, but is also their opposite. The bright colors and flashy camera work or "Tears of the Black Tiger" and "Citizen Dog" are exchanged for shades of brown, white and burnt orange. The camera framing is crucial because of what what is seen, and either off screen or not easily identifiable.

Also unusual is that "The Unseeable" is a period film. Taking place in the 1930s, the story is about a rural young woman who is seeking the husband who disappeared on a business trip. The woman, Nualjan, has been given the address of a house in a remote area that offers lodging. In the main house lives the owner, the mysterious Madame Ranjuan, who is pining away for her own husband. The household is run by Madame Somjit, a strict older woman given to walking around in the daytime with an old fashioned oil lamp. One of Nualjan's housemates is a young woman, Choy, who provides comic relief with her sassiness.

At least one major plot twist can be anticipated after the first half hour if not sooner. While "The Unseeable" is relatively subtle and restrained by Thai standards at least during the first hour, comparisons to such films as "The Haunting" or "The Innocent" is very misleading. Wisit has stated that the look of the film was inspired by the artwork of Thai artist Hem Vegakorn. If any western frames of reference are more apt, I would consider "The Unseeable" closer in spirit, as it were, to "Carnival of Souls" with a nod towards Mario Bava's "Kill, Baby, Kill". Too often, the soundtrack blares to instruct the audience to be startled. As the film was made primarily for a Thai audience, the concessions genre conventions emerge strongly during the last half hour. And yet what Wisit achieves a more genuine sense of poignancy that a less capable director could only wish for. Unlike too many Thai filmmakers who think nothing of playing down to their perceived audience, Wisit aims a bit higher. Wisit's artistic aspirations may have hurt "The Unseeable" at the box office, but it made for a much better film.
