The notorious schlockmeisters Troma, headed by Lloyd Kaufman and Michael Herz, were behind what must surely be one of the only golfing-related horror films ever made (unless you count the clubs wielded by the killers in Michael Haneke’s Funny Games), 1989’s Blades. The film was directed by Thomas R. Rondinella and is his only cinema-released feature to date and, as is typical with most Troma productions, the cast is mostly made up of jobbing b-movie actors. As the second tagline alludes to, the film is apparently a pastiche of Jaws with the shark replaced with a killer lawnmower wielded by a mysterious killer (and often show from the blades’ point of view).

The plot is described thusly on IMDb:

People are showing up sliced and diced at Tall Grass Country Club. Norman, the owner of the club, wants to avoid undue publicity on the eve of the televised pro-am tournament, and encourages new pro Roy to get to the bottom of the killings quietly. Roy has a history of alcohol problems since he choked while playing a big tournament years before, and Kelly, who feels she should have been hired as the new pro, isn’t making the situation easier for him, insisting they cancel the tournament until the killer can be stopped. After a seedy character named Deke Slater is arrested, the owner relaxes, but Roy and Kelly begin to feel that Deke’s rantings about a runaway lawnmower aren’t so far-fetched after all, and after Deke is released the three of them prepare for a battle to the death out on the uncharted fairways.

The film was apparently only released in a small handful of US cinemas before heading to video and HBO soon afterwards. I may be wrong but I don’t believe it ever saw release over here in the UK.
