There have been several movie adaptations of the books of Jonathan Stark (AKA Donald E. Westlake) featuring his career criminal lead character, Parker. Sadly not all of them have fared well, either critically or at the box office. Many have deviated from the source material, often just using mere aspects of the original plot as the basis of their screenplay. Perhaps the most successful of these has been Point Blank (1967), directed by John Boorman and starring Lee Marvin. Slayground sadly follows the pattern set by previous adaptations. It changes several character names and takes two main elements from the source text and uses them as a premise. Specifically, a robbery that goes wrong which results in an accidental death and a climactic shootout in an out of season fairground. Due to the financing of the film, half of the story takes place in the US and the other in the UK. Much of the cast are British, resulting in a curious and at first glance somewhat incongruous film.
