In Sneakers (1992), Martin Bishop’s real surname before he changed his identity was Brice.
Martin Bishop, played by Robert Redford, leads a security-testing team that evaluates computer systems for weaknesses. His current name is an assumed identity: years earlier, he was Martin Brice, a young computer hacker who broke into systems with his friend Cosmo.
The past becomes important when Cosmo reappears and pressures Bishop’s team to recover a device capable of defeating modern encryption. Bishop’s former identity helps explain both his technical reputation and his reluctance to revisit his earlier life.
The name is easy to confuse with Bishop, the identity used throughout most of the film, or with Cosmo, his former hacking partner. Sneakers combines computer security, espionage and a character-driven story about consequences and trust.
