The Heightsbridge Television Universe

The Heightsbridge Television Universe is an umbrella title for a series of television shows produced by Ifan Barber for streaming service Netflix. There are currently 4 series under the umbrella, Heightsbridge General (2016 -present), a medical drama, Heightsbridge Law (2016 - present), a legal drama, The Hollow Tree Horror (2016 - present), a horror thriller, and Heightsbridge Blue (2017 - present), a police drama. In December 2017, a four show crossover event series entitled Heightsbridge Massacre was released, surrounding characters from all shows after a massacre occurs in the city.

Background
Ifan Barber joined Netflix in 2015 as a creator and consequently formed a plot line for a potential universe of shows broadcasted and streamed entirely on Netflix. 3 shows were initially commissioned and the critical and commercial success of the three led to a commissioning of a fourth regular series and a crossover event series, as well as a 3 year renewal of the original 3 series.

Production on Heightsbridge General began in July 2015, followed immediately by production on Heightsbridge Legal in September 2015. The Hollow Tree Horror began production in January 2016 and concluded in April, a week before Heightsbridge General's premiere.

A fourth series wasn't initially planned, and HBPD police officers were originally conceived as recurring characters on Heightsbridge Law. However, a positive fan and critical reaction to the characters led to a commissioning of a separate series. It is rumoured that a fifth series, entitled Heightsbridge Social, will deal with Heightsbridge's social service sector, although it is yet to be officially green-lit by Netflix.

Each show has eight primary characters and various recurring characters. Ifan Barber has been noted for casting predominantly women in his shows.

Characters from the universe often appear on multiple shows, the only character to currently appear on all 4 shows is Police Commissioner Richard Clark, who made his debut on Heightsbridge Law as a guest star and consequently recurs on Heightsbridge Blue, he has made guest appearances on Heightsbridge General and The Hollow Tree Horror. Gillian Anderson is currently the only actress to be a regular on more than one show, being a regular on the first season of Heightsbridge General as Dr Hannah Hathaway and then being the same character, this time the protagonist, on The Hollow Tree Horror.
