Cypher, the resentful member of Morpheus's team, was played by Joe Pantoliano. This actor would become best known as the unhinged mobster Ralph Ciferetto (who lost his head) on the trailblazing cable series The Sopranos. Afterward, Pantoliano would return to being a constantly-working bit player in film and TV. He went on to work constantly throughout the years and most recently starred in the 2014 film The Identical.
