This page contains information regarding Star Trek: Discovery, and thus may contain spoilers.

This page contains information specifically pertaining to the fourth season of Star Trek: Discovery, whose episode premieres were consecutively streamed on Paramount+ in the USA and broadcast on CTV Sci-Fi Channel/Z in Canada from 18 November 2021 through 17 March 2022, becoming permanently streamed in Canada on CraveTV the next day.

Earlier advertising indicated that this season would be made available worldwide via Netflix. Less than a week prior to the original release date, it was announced that this would not be the case and that the three previous seasons would be removed from the platform. This was due to the planned extended global rollout of Paramount+ sometime during 2022. [1] [2] As a consequence, season four was initially planned as a North American exclusive to begin.

On 24 November 2021, in response to widespread fan outrage, it was announced the series (including the fourth season) would be made available on Paramount+ in all foreign markets in which the service was already available on 26 November 2021. For a small number of other markets which do not have Paramount+ but do have the Paramount-owned online service Pluto TV, the episodes are made available on the same timetable. Despite this, Discovery still remains unavailble for a large number of international markets. [3] [4]

Background information

  • On 9 January 2020, Production Weekly included a fourth season in its listing of upcoming productions, although no official announcement had been made. [5] [6] [7] [8] One of the unofficial early reports had it that production was to start in early July 2020. [9]
  • On 2 March 2020 another early unofficial report had it that not only a fourth season was in the making, but also that it was to be produced back-to-back with a yet to be confirmed fifth season. [10] This turned out not to be the case, but the second season of franchise sibling Star Trek: Picard became produced back-to-back with its third season a year later.
  • On 12 August 2020 showrunner Alex Kurtzman had to concede that the COVID-19 pandemic crisis wrought havoc on the franchise production schedules, and that production for all shows were delayed, including that of Discovery's fourth season. [11]
  • It was only on 16 October 2020 that the fourth season was officially announced; production began on November 2 in the midst of the COVID-19 pandemic crisis. [12] [13]
  • In a January 2021 interview with Michelle Paradise, she stated that Gray's storyline will be followed up in season 4 and "That storyline is incredibly important to us." [14] She expanded on that in a separate interview stating "Representation matters. It matters to see a version of yourself on screen. It matters there are non-binary and transgender characters. It matters that there is a Black woman in the captain's chair. It matters that there is a gay couple on our show. We will continue to do that for the show, and the world we live in, but also, to honor the Star Trek legacy. And to be super clear, we will pay that moment off in Season 4. Gray will be seen. That promise will be paid off." [15]
  • The entire production crew numbered nearly 80 crew and cast. [16]
  • In the penultimate week of April 2021, production was suspended for two weeks due to suspected on-set COVID-19 exposure. The projected June production wrap was not expected to suffer adversely from the temporary shutdown. [17]
  • Filming wrapped on 23 August 2021. [18]
  • The premiere date was announced as 18 November 2021.
  • The escalating move in the ongoing "streaming war" by globally sidelining Netflix as the international disseminator of the series just days before the fourth season premiere, constituted a surprise for many fans outside North America. Much to their chagrin and anger [19] – which was shared by Discovery's cast and crew [20] – the international Discovery fanbase was now forced to await the launch of Paramount+ in one format or another in their territories sometime in 2022. [21] This was not the case for viewers in Scandinavia, South America, and Australia, where Paramount+ had already been operational since mid-2021, and where the fourth season was expected to be sooner available for viewing after its debut in North America. [22] [23]
  • The gesture of making the season available on Pluto TV in those European territories without Paramount+ was only a partial fix as the service was not available in a number of smaller European countries including Ireland, Belgium, Denmark, and the Netherlands.
  • It appears that the November 2021 one-sided termination of the Discovery streaming rights by ViacomCBS came with financial compensation for Netflix. [24]
  • The premiere of season four came without an official series renewal announcement as had hitherto been customary for the Kurtzman-era Star Trek shows, [25] which included Discovery's season four which had been officially announced the day after its third season debuted.
  • The renewal for a fifth season was eventually announced on 18 January 2022. [26]
