On Call Cast & Character Guide

On Call not only thrives on realism with its grounded portrayal of police procedures but also on the strength of its strong cast of characters. Reminiscent of gripping cop dramas like David Ayer’s End of Watch, Prime Video’s On Call has been created by Tim Walsh and Elliot Wolf. The two showrunners put their experience working on legal thriller shows, like Chicago P.D. and Law & Order: Criminal Justice System, on full display by diving deep into the day-to-day snags and challenges faced by two police officers, Traci Harmon and Alex Diaz.

While following a relatively linear storyline, the Dick Wolf police procedural series unfolds at a quick pace by restricting its episodic runtime to around 30 minutes. Although the series sticks to many conventions of the genre, its performances and compelling side-story beats are enough to keep viewers hooked throughout its runtime. Since On Call‘s cast members play a crucial role in making its drama and action more convincing, many viewers may be curious about who plays whom after watching the series.
