Brad Pitt's latest film "World War Z" was supposed to premiere in Brazil on Monday, but was cancelled due to political unrest.

Paramount Pictures Brazil released a statement, saying: "In light of the current and ongoing events taking place in Brazil, we will not proceed with red carpet arrivals. Everyone involved with World War Z send their respect and goodwill toward the people of Brazil at this time of national unrest."

National demonstrations rocked the country, followed by a smaller protest opposing increased bus fares in Sao Paulo, The Los Angeles Times reports.

The protests exploded after a police crackdown, and Brazilians took to the streets in growing numbers to voice anger over a wide range of issues, including spending on facilities for the World Cup, which Brazil will host next year.

Last weekend's opening of "World War Z" grossed $66 million during its first three days. It became Brad Pitt's biggest opening weekend ever. In international markets, where Pitt traveled to premieres in London, Paris and Moscow, the film grossed $45.8 million in 25 countries, The Los Angeles Times writes.

Interestingly, "World War Z" performed best in South Korea, bringing in $10.3 million.

Pitt had been scheduled to walk the red carpet in Brazil with "World War Z" director Marc Forster, who also did not head to Brazil.

Also, there are rumors that "World War Z" might have a sequel being planned in the near future, IGN.com reports.
