Sneakers is a 1992 caper film directed by Phil Alden Robinson, written by Robinson, Walter F. Parkes, and Lawrence Lasker and starring Robert Redford, Dan Aykroyd, Ben Kingsley, Mary McDonnell, River Phoenix, Sidney Poitier and David Strathairn. It was filmed in late 1991 and released in 1992. Lawrence Lasker and Walter F. Parkes first conceived the idea for Sneakers in 1981, while they were doing research for the script of Wargames. In early drafts of the story, the character of Liz was an employee of the bank into which the team breaks during the film's opening scene, rather than Martin's ex-girlfriend. The role was changed because Lasker and Parkes believed that it took too long for her character to develop. Once Robert Redford was attached to the picture, his name was used to recruit other members of the cast and crew, including the director Robinson, who had little initial interest in the project but had always wanted to work with Redford. At one point during the project, Robinson received a visit from men claiming to be representatives of the Office of Naval Intelligence, who indicated that for reasons of national security, the film could not include any references to "a hand-held device that can decode codes". Robinson was highly concerned, as such a device was a key to the film's plot, but after consulting with a lawyer from the film studio he realized that the "visit" had been a prank instigated by a member of the cast, possibly Aykroyd or Redford.
