Kevin Costner, 46, and Cuban leader Fidel Castro met for seven hours Monday night, following a special Havana screening of the Costner picture “Thirteen Days,” reports Reuters. The movie concerns the Cuban Missile Crisis, which involved Castro, J.F.K. and some Russian rockets back in the early 1960s. “I shouldn’t be speaking for the president, but he responded to the film very favorably, and we had a very interesting discussion afterwards,” Costner’s spokesman, Stephen Rivers, told the news service. In the U.S., “Thirteen Days” received respectable to mixed reviews but did little business.
