This queasy sex comedy follows two middle-aged men (Michael Caine and Joseph Bologna) who spend a month to Rio with their two nubile daughters (Demi Moore and Michelle Johnson). Caine's wife (Valerie Harper) pulls out of the trip, saying she wants to think about their marriage, and then spends a month at Club Med. Once in Rio, Bologna, who is going through a messy divorce, heads for the city's nightlife to chase women. Caine is less than enthusiastic about this but soon finds he's being seduced by his friend's daughter. At this point BLAME IT ON RIO turns into a most uncomfortable film, leeringly depicting an affair with decidely icky undertones of incest and pedophilia. Between gratuitous (if titillating) nude scenes and a succession of lame soundtrack songs, there are plenty of travelogue shots to pad out the thin narrative line. Caine looks embarrassed through the entire film, as well he might.
