More than 100 actors auditioned for the role of Doggett, but only about ten were seriously considered. Lou Diamond Phillips, Hart Bochner, and Bruce Campbell were among the ten. The producers chose Robert Patrick. Carter believed that the series could continue for another ten years with new leads, and the opening credits were accordingly redesigned in both seasons eight and nine to emphasize the new actors (along with Pileggi, who was finally listed as a main character). Doggett's presence did not give the series the ratings boost the network executives were hoping for. The eighth-season episode "This is Not Happening" marked the first appearance of Monica Reyes, played by Gish, who became a main character in season nine. Her character was developed and introduced due to Anderson's possible departure at the end of the eighth season. Although Anderson stayed until the end, Gish became a series regular.
