Original cast member Paul Blackthorne may be done with Arrow, but fans will still be able to see him on television.

The veteran actor will costar on the new NBC series The InBetween. According to Deadline, Blackthorne's casting in the pilot was kept secret so as not to prematurely reveal his departure from Arrow.

Given a series order by NBC, The InBetween stars Harriet Dyer as Cassie Bishop, a woman who can see and communicate with the dead. Bishop decides to put these supernatural skills to use and helps the police and FBI in solving murders.

Blackthorne co-starred for six seasons of Arrow, playing Quentin Lance, father of Laurel and Sara Lance. During his tenure on the CW drama, Lance rose through the ranks of the Star City police department to become a captain before succeeding Oliver Queen as mayor.
