NEW UPDATES ON PRISON BREAK SEASON 4
Season 4 will premiere on September 1, 2008. Producers have reported that Sara Tancredi, who was believed to have been killed in season 3, will be making a return as a regular cast member in season 4. It is also mentioned in promotional information that the season will involve an FBI agent (Michael Rapaport) teaming up with the protagonists Michael and Lincoln and several other characters to bring down the Company once and for all. This season, instead of a break out, they will be making a break in. The story includes a new character F.B.I Agent Wyatt (Cress Williams) investigating whether or not the main characters are actually recaptured and are in a maximum security prison as was reported. Also, A Fox rep for Prison Break confirms that one or possibly two of the show’s main characters will die in the season premiere, with one of the actors leaving the series for good. Another character that will help fill the gap left by the dead characters is Roland Hiroyuki Liao a hacker from Brooklyn who gets under the team’s skin, but whose technical knowledge they require.
