Harrow Season 4 - Will It Ever Happen?

As long as television is a viable medium for storytelling, medical dramas will continue to air. While this isn't a rule in the strict sense of the word, it appears to remain true given the ubiquity of the genre over the course of recent TV history. Arguably the most influential series in the genre is "ER," which premiered in 1994 and more-or-less kick-started the medical drama trend that continues into the present day. Furthermore, members of its ensemble cast went on to successful Hollywood careers in the wake of their tenure on the series. Since then, the likes of "House, M.D.," "The Good Doctor," and plenty more have remained among some of the more successful shows on television.

"Harrow," which premiered on Australian network ABC in 2018 and was distributed internationally by Hulu shortly after, can count itself among the perpetually growing number of TV medical dramas. Like "House" before it, Harrow's namesake is its protagonist, a doctor who doesn't always play by the rules but remains committed to his patients first and foremost. Unlike in "House," Dr. Harrow's patients are generally dead, meaning that Harrow is investigating murders after the fact rather than treating living human beings.

The third season of "Harrow" concluded on April 11, 2021. Here's everything we know so far about a hypothetical "Harrow" season 4.

"Harrow" producers at Australian network ABC have yet to confirm whether or not a fourth season of their hit medical drama is in production. However, there's no reason to believe the series won't continue for more episodes, either, barring an announcement of its cancellation.

Per Deadline, Season 3's renewal was announced in October 2019, about three months after its second season concluded. Its third season then premiered about 16 months after that, meaning that the total turnaround time between Season 3's finale and Season 4's debut is stretching into the two-year plus territory. With no new episodes airing since 2021, a premiere sometime in 2024 for "Harrow" Season 4 — at the absolute soonest, considering possible pandemic related delays — could be in the offing.

Structurally, the drama on "Harrow" is generally episodic, with ongoing season story arcs playing out amidst its individual self-contained plot-lines. Throughout Season 3, Dr. Harrow attempted to reconnect with his supposed son James, who he had previously thought dead. In the Season 3 finale, James is kidnapped, and Dr. Harrow, Fern, and Callan work to negotiate his release. After saving James, however, his mother Tanya reveals to Dr. Harrow that James was never actually his son, and the claim was merely an attempt by Tanya to secure Dr. Harrow's involvement in her life.

Since the season-long story arc following Dr. Harrow's relationship with James is wrapped up as of the conclusion of Season 3 and no other significant plot threads remain unresolved, Season 4 would most likely introduce an entirely new source of drama into the various lives of Dr. Harrow and company.

Ioan Gruffudd stars in "Harrow" as the titular Dr. Daniel Harrow, meaning that his return is all but guaranteed should the series be renewed. Gruffudd is very recognizable for his bit part in "Titanic" as Fifth Officer Lowe. He also starred as Reed Richards in the 2005 "Fantastic Four" film as well as its 2007 sequel.

Without an announcement of a fourth season of "Harrow," it's hard to predict who will be appearing alongside Gruffudd in Season 4. Presuming the return of the entirety of the series' central cast as of the end of Season 3, Season 4 should also feature Ella Newton as Dr. Harrow's daughter Fern, Hunter Page-Lochard as her boyfriend Callan Prowd, Darren Gilshenan as fellow Queensland Institute of Forensic Medicine examiner Lyle Fairley, Jolene Anderson as niece Dr. Grace Molyneux, and Damien Garvey as Queensland Police's Criminal Investigation Branch Detective Senior Sergeant Bryan Nichols.

"Harrow" is distributed by ABC International, the global offshoot of ABC, one of the major Australian TV networks. As such, the first three seasons of "Harrow" from 2018, 2019, and 2021, aired on the broadcast network in Australia, and viewers living in that country can catch up and watch the whole 30-episode run on ABC's iview streaming service.

ABC in the United States is a different entity from Australian ABC, a subsidiary of Disney, which also operates the Hulu-streaming service. It's there that American viewers can check out "Harrow," as all three existing seasons of the Australian crime drama are available to view at no additional charge to Hulu subscribers. Elsewhere for North American fans, the first 10 episodes of Season 1 of "Harrow" are up for individual download via Amazon's Prime Video platform at a cost of $1.99 for standard definition and $2.99 each for HD versions.
