Elite Squad: The Enemy Within is a 2010 Brazilian crime film directed, produced and co-written by José Padilha, starring Wagner Moura. It is a sequel to 2007 film Elite Squad. It furthers the plot of a semi-fictional account of BOPE (Portuguese: Batalhão de Operações Policiais Especiais), the special operations force of the Rio de Janeiro Military Police, with a focus on the relationship between law enforcement and politics. The film was released in Brazil on October 8, 2010.
Having enjoyed public and critical acclaim, Elite Squad: The Enemy Within is the all-time largest box office ticket seller and highest-grossing film in Brazil, ahead of Dona Flor and Her Two Husbands and Avatar, respectively. The film was selected as the Brazilian entry for the Best Foreign Language Film at the 84th Academy Awards, but it did not make the final shortlist.
