Tony Shalhoub has joined the cast of CBS’s upcoming crime drama Einstein, reuniting the actor with key members of the creative team behind Monk. The casting adds another familiar name to the network’s new procedural series and brings together several figures associated with the acclaimed detective show.
The series centers on Lewis Einstein, a “brilliant but directionless professor.” As he becomes involved in criminal investigations, his analytical skills and unconventional outlook prove useful to law enforcement. The show follows his efforts to help solve difficult cases while navigating the challenges in his personal and professional life.
Shalhoub will appear in a recurring role as Jack Einstein, the father of Lewis .
The addition of Tony Shalhoub to Einstein continues a professional relationship that began with Monk. Series creator Andy Breckman developed the CBS adaptation and wrote the pilot episode. Randy Zisk directed the pilot and serves as an executive producer. Both men worked closely with Shalhoub during Monk’s eight-season run on USA Network.
A New CBS Adaptation of an International Series
The CBS series is based on the German drama Einstein, which was created by Martin Ritzenhoff and Matthias Dinter. The original production ran for three seasons and centered on a highly intelligent descendant of Albert Einstein who becomes involved in criminal investigations.
