This film, Invaders from the Deep, is another compilation by ITC New York from original TV episodes, this time from the Gerry Anderson series Stingray. 'Hostages of the Deep', 'Emergency Marineville', 'The Big Gun' and 'Deep Heat', are the episodes used and the producers of the movie are generally faithful to the original material. However, Stingray's sting missiles are replaced by some ghastly green lasers complete with a stupid electronic sound effect. This is deeply irritating and looks incredibly false, when they couldn't just leave it as it was I will never know. The ending title is also frustrating, as the Stingray theme is paired with music from Thunderbirds and the Beatles tune We all live in a Yellow Submarine, I mean why? It has no connection to Stingray whatsoever. Having said this, it is one of the better movies and it is an OK representation of the series.
