The Psychotronic Film Society’s ongoing weekly series of underappreciated features continues with the ultra-rare 1949 Japanese sci-fi action picture “The Invisible Man Appears.” Produced by a relatively small, independent studio and never released outside of Japan, this low-budget B&W flick clearly uses Universal Pictures’ 1933 hit “The Invisible Man” starring Claude Rains as its inspiration, as many of its key sequences and special effects are openly reminiscent of that beloved “pre-code” horror-thriller. However, as one might expect, this adaptation injects some distinctly Japanese subject matter into the proceedings — namely, an espionage subplot involving Japanese organized crime.

When a brilliant scientist develops a special formula that renders people invisible, a gang of jewel thieves becomes obsessed with acquiring the formula to help them steal a valuable diamond necklace. Mixing tension, action, thrills and even a bit of romance, “The Invisible Man Appears” (which was followed by at least two sequels in Japan) is a minor gem of its genre and almost completely unknown outside of its home country. The PFS will screen the full, uncut version in spoken Japanese, with English subtitles (sourced from a vintage, long out-of-print Japanese laserdisc).
