Game development began in 2004 at Rockstar Vienna. In 2006 Rockstar Vienna was closed, and Rockstar London took over development. Rockstar Toronto developed the Wii version. Five voice actors have confirmed to have recorded dialogue for the game. Even though two of them chose to remain anonymous, the third voice actor James Urbaniak publicly announced it on his blog on March 16, 2006, only to remove it days later. Of the other two voice actors said to have recorded dialogue for the game, one of them also recorded dialogue for the original Manhunt, like Urbaniak.
