Trivia

This was the first of eight feature films for the independent Zenith Pictures, the production company formed by producer Edward Small to make low-budget films for release through United Artists. All of their productions during the 1960s were directed Edward L. Cahn.

That big convertible driven by Holly Taylor (Pat Blair) is a 1960 Lincoln Continental Mark V Convertible. Only 2,044 were made of this car that weighed over 2.5 tons and was nearly 19 feet long (5.77 m). MSRP was $7,056 ($71,000 in 2022) In excellent condition in 2022 an example of this car could be worth over $100,000.

The plumber's van is a 1960 Chevrolet C-10 Apache Panel Van. The big white car rented by Det. Scott Harper (Ron Foster) is a 1960 Mercury Montclair Sedan.

They tried to boost the boxoffice by advertising this as "not suitable for children".

This was one of Edward L. Cahn's many one-week wonders he directed during this period.

Although shot in academy 1.37:1 aspect ratio (for later television airing) the theatrical -- or *intended* (by the studio, producer, director and/or cinematographer) -- aspect ratio of this film is 1.85:1 widescreen. Most modern 16x9 (1.77:1) televisions have a "zoom to width" picture option, essentially allowing the viewer to see the film as the director and cinematographer originally planned. It is easy to spot films shot this way since all the titles and credits will still fit when properly cropped (they stay in the "middle" of the frame vertically), and there is an unusual amount of "headroom" above the actors in medium and close-up shots when viewed uncropped. Quite often "mistakes" -- like seeing equipment in the top or bottom of the uncropped frame -- would never have been seen by a theater audience.
