NEW YORK  - A federal judge has reaffirmed his decision to dismiss a lawsuit accusing actor Sylvester Stallone of copying someone else’s screenplay to make his popular 2010 movie “The Expendables.”US District Judge Jed Rakoff in Manhattan on Thursday rejected claims of copyright infringement damages by Marcus Webb, who contended that the movie’s screenplay contained 20 “striking similarities” to his own “The Cordoba Caper.”Webb claimed that both works had similar plots, and involved hired mercenaries in a Latin American country that was home to a villain dictator named General Garza. But Rakoff said no reasonable juror could find that the works were so similar as to eliminate the possibility that Stallone crafted his screenplay on his own.
