Four years after Oscar-winning director Oliver Stone filmed a documentary on Cuban despot Fidel Castro, the U.S. issued a fine for violating the U.S. embargo to the communist island nation.

Stone produced two works in Castro’s prison nation.

First, he shot “Comandante” for HBO. The film could not be aired because even HBO thought it was too soft on the Cuban dictator.

Then Stone shot “Looking for Fidel” and included interviews with employees of the U.S. Interests Section in Havana.

At the San Sebastián Film Festival in Spain, where “Looking for Fidel” was being screened, Stone said, “Castro is one of the wisest men there are; he is a survivor and a Quixote. I admire his revolution, his faith in himself and his honesty.”

According to the U.S. Treasury Department Office of Foreign Assets Control, Stone`s production company, Ixtlan, and four other unidentified individuals were fined $6,322,20 for dealing "in services in which the government of Cuba or a Cuban national has an interest.”
