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 10 February 2022, becoming permanently streamed in Canada on CraveTV the next day. It was originally announced that the rest of the world had to wait for the worldwide rollout of Paramount+ sometime during 2022, as Star Trek owner ViacomCBS began to phase out streamer Netflix from the franchise mix, starting in September 2021. [1] [2]

However, on 24 November 2021, in response to widespread fan outrage, it was revealed that the series, including the fourth season, would be made available on Paramount+ in all markets in which the service was already available on 26 November 2021. For those markets still without the service, the fourth season episodes will premiere on the free ad-supported streaming service Pluto TV on the same timetable. [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] [9]
  • 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. [10] [11]
  • 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." [12] 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." [13]
  • The entire production crew numbered nearly 80 crew and cast. [14]
  • 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. [15]
  • Filming wrapped on 23 August 2021. [16]
  • 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 nasty surprise for many fans outside North America. Much to their chagrin and anger [17] – which was shared by Discovery's cast and crew, incidentally [18] – the international Discovery fanbase was now forced to await the launch of Paramount+ in one format or another in their territories at an indeterminate date, sometime in 2022. [19] 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. [20] [21] As stated in the introduction though, the fan outcry forced the franchise to re-evaluate its position on the roll-out of the season in foreign markets.
  • It appears that the November 2021 one-sided termination of the Discovery streaming rights by ViacomCBS came with financial compensation for Netflix, [22] which could only mean that the streaming rights contract had not expired yet, and that some sort of pay off was called for, most likely a payback of the season four production costs, advanced by Netflix. But this also meant that external funding for Discovery had come to an end and that the franchise from now on had to bear the production costs in full on its own, in the process explaining the lack of an official series renewal announcement at the start of season four as has been customary for the other Kurtzman-era Star Trek shows.
