Sock Latin-American one-reeler, lacking a dull moment. The annual Mardi Gras of Brazil is excuse for parading Latin-American artists and atmosphere, with newsreel shots of actual Rio de Janeiro festival trimly dovetailed into production material. Singing of Elsie Houston, Brazilian soprano, fits nicely into the opening sequence while the wild gyrations of Jose and Lolita Vega are nearly as primitive as some of Brazilian stepping captured (but a mere flash) by the newsreel camera. Fernando Alvarez supplies change of pace by introducing the current South American carnival anthem, Carolina. Exciting enough to make on want to visit Rio at carnival time. Another to Les Roush's credit.
