The Killers Are Our Guests opens with a daring daylight jewelry store robbery. One of the robbers is shot during the escape. The band of robbers is forced to seek medical attention for their partner and end up at the isolated villa of a doctor and his wife. Forced to comply, the doctor does his best to patch up the wounded robber. The baddies hold the pair hostage until they're able to hit the road. It's a nightmare of a night as the doctor and wife are threatened with their lives, the wife is raped, and, in the end, most everyone is killed.
Overall, I found The Killers Are Our Guests an above average piece of entertainment. I'm not sure how I'd classify the film, but I'm going to go with poliziotteschi or Euro-crime. The film features plenty of atmosphere as the robbers harass and threaten the couple. The movie never goes as far as something like Last House on the Left, but it has a similar cramped, ominous feel to it. I really started to feel for the doctor's wife. Either through choice or force, she has sex four times during the night. And when it's not by choice, it's not very pleasant. While the police seem ineffective throughout, the way the police ultimately catch their prey is nicely handled and provides an unexpected twist. The acting is solid. Genre regulars Anthony Steffan, Luigi Pistilli, and Margaret Lee are as good as I've come to expect. It's always nice to discover a "new" movie with Margaret Lee. The rest of the cast is more than adequate. If it weren't for some fairly long stretches in the second act where the film almost grinds to a halt, I could have easily rated The Killers Are Our Guests higher.
