Trivia

According to Jane Allen in her book "Pier Angeli: a fragile life", Director Guy Green had a hiatus between completion of Sea of Sand (1958) and the filming of The Angry Silence (1960), and picked up the script for what he considered a "potboiler". It also gave him the chance to work with Sir Richard Attenborough again before their next movie. The producers instructed him to find a Pacific-style desert island with palm trees fast, and he went with the designer to London Airport. Unable to get tickets for Majorca, on a whim they flew to Las Palmas in the Canary Islands, and found the ideal location at the southern tip of the island: just a beach with a few trees.

The location shoot was reported to be very happy. Pier Angeli was relieved to be away from press attention following her divorce from Vic Damone, and was often taken out to dinner by Director Guy Green and Sir Richard Attenborough, always insisting her other female co-stars join them too. On the strength of the friendship, Green and Attenborough cast her in The Angry Silence (1960).

There is an early colorized version of this movie available (from Renown Pictures). It has that usual hand-colored pastel quality, but with a very limited palette. In the card-playing scene at the start, the 10 of diamonds is gray not red.

In 1960, Universal-International distributed this movie on a double bill with Dinosaurio (1960).

The casting of Eddie Constantine came as part of the producers' deal.
