John Rue (Truck guy) previously played the role of Desk Sgt. Ludlow in episode 8.19, Florida (2007).
Some critics felt that Isabelle Huppert, then 57, was perhaps too old to be playing the mother of a young child.
D.W. Moffett also had a recurring role in another Dick Wolf show, Chicago Med, as Cornelius Rhodes (father of dr. Connor Rhodes).
