"Manhunt" is the season premiere of season two of the American television series Prison Break and the twenty-third episode overall. The episode was first aired on August 21, 2006 in the United States. It is written by series creator Paul Scheuring and directed by Kevin Hooks, who directed the season finale of season one, "Flight". William Fichtner is introduced as a new regular cast member, whose character is assigned to track down the eight escapees from Fox River State Penitentiary. The role of Terrence Steadman was recast to Jeff Perry, who replaces John Billingsley as the brother of Caroline Reynolds (based on how little time the character was seen clearly, series creator Paul Scheuring jokingly questioned in interviews whether Billingsley had ever even been on the show to begin with).
