The CW is making a casting change on its newly picked up drama series In the Dark, from CBS TV Studios and Ben Stiller’s Red Hour Films. Austin Nichols, who co-starred in the pilot, is leaving; his role, Dean, will be recast.

Written by Corinne Kingsbury and directed by Michael Showalter, In the Dark centers on Murphy (Perry Mattfeld), a flawed and irreverent young woman who just happens to be blind and is the only “witness” to the murder of her drug-dealing friend, Tyson. When the police dismiss her story, she sets out with her dog, Pretzel, to find the killer while also managing her colorful dating life and the job she hates at Breaking Blind — the guide-dog school owned by her overprotective parents.

Dean is a salt-of-the-earth cop. He’s called in to investigate when Murphy claims she has discovered Tyson’s dead body in an alley. He’s put on the case because he has a blind daughter, and it’s thought that he may be sensitive to Murphy’s situation. He also initially thinks that Murphy’s claim was the result of a drunken delusion. But as Murphy cleans up her act and presses the police to investigate, Dean begins to lend credence to her claims.

Brooke Markham and Keston John co-star.
