"Crash Twinsanity" began development as "Crash Bandicoot Evolution" and was intended to have a more serious tone than previous games. The similarity of the game's premise to "Ratchet & Clank" convinced Traveller's Tales to restart production and create "Crash Twinsanity" as a comedic title in which Cortex would be teamed up with Crash as a means of exploring his character. The game marks the debut of Lex Lang as the voice of Cortex, replacing previous actor Clancy Brown. Various concepts were removed from the game during production due to time constraints, but were incorporated into the final game as unlockable extras.
