It is reported that actress Sarah Wayne Callies will return as Dr Sara Tancredi for the fourth series of 'Prison Break'.
Fans had thought that Callies' character was killed during season three because of a scene with a Polaroid of her head in a box.
Speaking to E! about Callies' return, the show's executive producer Matt Olmstead said: "It wasn't because of the fans that we did that, but it was the combination of the fans' reactions on the boards and emails, and people we, the writers, know personally would ask about it. And that led us all to have conversations internally, about the fact that there were a lot of people out there asking, "Is she really dead?"
He continued: "We knew internally that when we didn't get Sarah Wayne Callies to come back in season three and be there to portray her character's death, as soon as it was written and filmed and we saw it on screen, we knew that it was actually a way you could describe how this wasn't Sarah's head in the box, basically. But at that point, we were going forward with other stories, so we kind of put that on the back burner."
He added: "But throughout that time we watched how people externally were really talking about what we thought might be the case, internally: The question of, "Is Sara Tancredi really dead?" So throughout season three we were mindful of references we'd make to and who took credit for killing her and all kinds of stuff regarding her death."
