On the Internet Movie Database this film has 3 different directors listed, I wonder if that's the reason why it feels a lot like two different movies glued together as one. The first one is a nice comedy about two brothers (Tognazzi and Venditti) who apparently have an habit of falling for the same women, and that's definitely not the only matter of conflict in the family. This part is extremely enjoyable, and less predictable than many other romantic comedies. Then, unexpectedly, the film drifts towards a totally different perspective, leaving the viewer somehow puzzled (what's the reason for moving the action to South Africa? A co-production agreement, most likely, but definitely not an artistic choice). Without giving up much of the plot, let me just say that if after one hour you suddenly feel as if you're now watching a totally different film, don't worry, you're not the only one.
