'Party Line' is a camp 80's slasher flick that features a dated yet fun premise that involves the adult telephone line, a concept that will be completely lost on the younger generation, but here its used quite effectively as part of the storyline. The movie is pretty standard yet fun at the same time and competently shot with a tight pace and enough entertainment value to keep you interested throughout.
The plot = A pair of rich siblings Seth (Leif Garrett) & Angelina (Greta Blackburn) are crazed killers who use the party line to lure married men to their deaths. While at the same time a detective Dan (Richard Hatch) is assigned to the case with a new partner Stacy (Shawn Weatherly), can they catch the killers in time.
The performances in this are really strong with Leif Garrett stealing the show as the disturbed cross-dressing Seth, he's easily the most entertaining aspect of the movie. The sister played by Greta Blackburn also gives an entertaining performance and the pair have great chemistry together and every time the movie is revolving around these its hell of a good time. Richard Hatch and Shawn Weatherly are fine in their roles, but their characters aren't quite as engaging as the siblings. Richard Roundtree is always a joy to watch and brings a certain spark to the cast of characters.
The only thing that lets things down a bit are the scenes involving the police which can be a bit dull at times, but the party line scenes offer enough fun and nostalgic moments that are very contrived especially with the ridiculous and corny dialogue. There's enough sleaze and nudity to hold your attention most of the time, but the movie could have done with a bit more suspense and more bloody kills. However the movie is still a fun time, despite a few flaws.
