In many ways, if you add in sex scenes, Blame it on Rio has the potential of being a soft-core adult movie. The subject matter is very risky for an early 80's comedy. Michael Caine stars in and puts his reputation on the line as the comedic element in this adult drama. Although comedy is thrown into the mix from time to time, Blame it on Rio is in many ways, a dark comedy. Much of the night scenes are in fact dark. Too dark to some standards, you can hardly make out the actors on screen. The beach scene alone could have been re-shot due to stupidity in the lighting department. Valerie Harper also makes an appearance alongside a very young Demi Moore who, unlike the eye candy of the movie, Michelle Johnson is reserved. Since Rio, Michelle Johnson slowly faded away, returning to do a small role from time to time. Her popularity from Rio could have and should have made her a top actress / ornament in Hollywood. Sadly, much like this movie, it has lost its strong youth audience to other movies with more nudity and less comedy.
