Joel Silver sets up 'Unknown White Male'

Thriller in development at Warner Bros.

Joel Silver's Dark Castle is developing "Unknown White Male," a thriller about a doctor who awakens from a coma to finds he seemingly has been replaced by another man, for Warner Bros. to market and distribute.

Jaume Collet-Serra, who is helming upcoming child-centric thriller "Orphan" for Silver and Warners, is attached to direct.

According to the logline, "Male" centers on a doctor who, when visiting Berlin with his wife, gets into a car accident that leaves him in a coma; he then awakens to find out that someone has taken his place, leading him on a frantic quest to discover the truth.

Karl Gadjusek, who penned the home-invasion drama "Taken" that's in development at Overture, wrote a draft of the script.

The CAA-repped Collete-Serra also directed "House of Wax," Warners' 2005 horror pic that starred Elisha Cuthbert. In addition to "Taken," the WMA-repped Gadjusek also counts the TV series "Dead Like Me" among his credits.
