This film is based on the british tv series of the same name and was imitated -badly I am told - in america as 'Three's Company' although I have not seen this. It fits into part of the series even though it was seperately comissioned and scripted and produced. Athough the british series is good it unfortunately ends with Chrissy (Paula Wilcox) falling for another man when we all thought and hoped that eventually she would go off with Robin (Richard O'Sullivan) and another, fairly dreadful, series was made continuing Robin Tripp's life in 'Robin's Nest' where he was the chef in his own struggling restaurant. I have detracted from the point now which is this is a very enjoyable film, very funny, and you'll end up fancying the female characters (Paula Wilcox, Sally Thomsett) by the end,well if your like me.
