Brazil is perhaps the best of the handful of US films made by singing sensation Tito Guizar. In typical screwball-comedy fashion, the plot is set in motion by authoress Nicky Henderson, who has hit the best-seller charts with her latest tome, Why Marry a Latin? While researching her next book in Rio De Janeiro, she finds out "why" when she meets handsome songwriter Miguel Soares. Upon learning about Nicky's book, Miguel decides to teach her a few lessons in the affairs of the heart. Edward Everett Horton is also on hand, twittering his way through the role of a well-meaning buttinsky. Thanks to the "Good Neighbor" policy of the 1940s, South American musicals were a glut on the market, but Brazil was good enough on its own merits to pay its way at the box office.
