BLAME IT ON RIO(1984)
One of those movies that you wonder how it ever got
made(kind of like Beau Pere, Pretty Baby & Blue
Lagoon)!! Two gentlemen friends take a vacation together
to Rio along with their daughters! Both daughters are
quite lovely, and one thing leads to another and there's
much hanky panky going on!! A comedy but still quite
a serious subject! Don't worry, everything works out
in the end!!
And Yup, there's nudity!! B+
From IMDb.com:
Featherweight treatment of a potentially serious subject,
filled with too many stale jokes and too much Brazilian
folklore. The capable cast gives this film whatever value
it has, especially Michael Caine, who is working here
below his usual high standards, but still manages to
be extremely likable. (**) - gridoon
