This is not an actor's film but a musician's one, such as those starred by Elvis Presley or by The Beatles. Singer and composer Roberto Carlos is very famous in Brazil and collected hits in the 60's and 70's. This is his last film and the only one in which his character was not himself. "300 Kilometers/hour" is an underdog car racing movie (the mechanic wants to win a car race and impress the girls he loves), full of clichés, merchandising and a pinch of sexism. The worst moment is not central, but politically important and unforgivable: the character portrayed by singer Erasmo Calos - the main partner of Roberto Erasmo Carlos in his career projects - shouts "Hail Brazil! Love it or leave it!"; "Love it or leave it" was the slogan of military dictatorship, which was in its most violent moment when the film was launched. Though, the movie is neither bad, nor as predictable as it seems at first sight (the end is not fantastic but surprisingly interesting). Some of the actors - Raul Cortez, who portrays the boss and pilot, Reginaldo Faria, the owner of the broken car, and Flávio Miggliacio, who plays the truck driver - were among the best in the country. For car lovers, it may be attractive to see in this film the red Avallone Chrysler or the orange Dodge Charger R/T 1971.
