Some explanation is required for Screamers, a US version of an Italian fantasy called Island of the Fish Men. The original film is a handsomely mounted piece by Sergio Martino, who pulled in an impressive cast including Barbara Bach, Richard Johnson and Joseph Cotton for an Island of Dr Moreau-type action adventure. The lack of exploitation elements here (no sex, little blood) seem to have inspired Roger Corman to buy the film, chop thirty minutes out and add in a specially-shot prologue which has more of a splatter/slasher movie vibe as a group of sailors led by Cameron Mitchell and Mel Ferrer are picked off by a much more homicidal branch of the fish-men team. The gore effects by Chris Walas are very 80’s, and both sections of the film are well-done, even if there’s not much connection in terms of story of theme. With exploding volcanoes, armies of fish-men and a diving-bell trip to Atlantis, this is much more of a Saturday matinee adventure than an adult horror, and the vigour of Martino’s story-telling is something to behold.
