The fourth series of the British science fiction programme Primeval began on 1 January 2011 and concluded on 5 February 2011 after airing seven episodes. Primeval follows a team of scientists tasked with investigating the appearance of temporal anomalies across the United Kingdom through which prehistoric and futuristic creatures enter the present. Following the departures of key actors in the third series and the inability of some of the actors to return for the fourth series, several new main cast members were introduced, including Ciarán McMenamin, Ruth Kearney, Alexander Siddig and Ruth Bradley.

After the broadcast of its third series, Primeval was cancelled by ITV in June 2009 due to financial issues but it was renewed for two more series after ITV and the production company Impossible Pictures worked out a deal for co-funding with UKTV. The fourth and fifth series were produced concurrently in 2010. The writing of the fourth series was focused mainly on resolving lingering plotlines, introducing the new characters, setting up plot elements in preparation for the fifth series, and developing the remaining characters from previous series further. The fourth series marked the first time Primeval was filmed in HD and also the first time the visual effects of the series were created by The Mill rather than Framestore (responsible for the previous series).

The fourth series achieved somewhat disappointing ratings compared to preceding series, averaging about four million viewers (compared to the five million of the third series and the over six millions of the first two series). Critical reception was also more mixed than previously, with criticism leveled at the overall slow narrative progression and the manner in which the final episode resolved the storylines. Opinions varied on the new characters, with some reviewers enjoying the team dynamic and others finding them to be poorly established. The development of the returning characters was more universally liked and the visual effects received universal praise, many critics finding them to be the best of the series thus far.

Synopsis The fourth series of Primeval is set an extended period of time, approximately twelve months, after the third series. The deaths and disappearances of several key ARC (Anomaly Research Centre) personnel has seen the British government lose faith in the operation, placing it under a partnership, partially funded by the government and partially by the entrepreneur Philip Burton (Alexander Siddig). The ARC is still run by James Lester (Ben Miller), but he now has to begrudgingly accept Burton's involvement and operate out of new lodgings in Burton's industrial complex. The disappearances of Danny Quinn (Jason Flemyng), Connor Temple (Andrew-Lee Potts) and Abby Maitland (Hannah Spearritt) has forced the ARC to recruit new personnel, including the new field leader Matt Anderson (Ciarán McMenamin) and the field coordinator Jess Parker (Ruth Kearney). In addition to being explained in promotional material, the events behind the third and fourth series were also revealed through a series of short webisodes released on the Primeval website.

Cancellation and revival Despite a successful third series, Primeval was cancelled by ITV executive Peter Fincham on 15 June 2009 for financial reasons; due to the Great Recession and declining advertising revenues, ITV was at the time only two weeks from going bankrupt despite already cancelling several programmes. ITV declined to recommission Primeval for a fourth series despite Impossible Pictures, the production company behind the series, proposing numerous different options, such as producing the series cheaper (for £600,000 per episode) or offering first-run rights to a rival channel. The cancellation was likely primarily motivated by the effects budget; Primeval cost around £8 million per series and ITV could not claim all of the money earned by the series due to it being produced independently by Impossible Pictures.

Upon receiving the news of the cancellation, the production team of the series stated that they had "every intention of keeping Primeval alive in other ways". During the production of the third series, the producers had at no point expected that Primeval would not return for a fourth series, stating in subsequent interviews that they would not have left as many of character's fates up in the air had they known of the threat of cancellation. Three months after the cancellation, Fincham recommissioned Primeval. The "resurrection" of the series was made possible through a new deal made by Impossible Pictures, in which the series would be co-produced by both ITV and UKTV (with the costs shared), with additional funding also being provided by BBC Worldwide and ProSieben. The deal secured the making of thirteen new episodes, split into a fourth and fifth series. The fourth series would air on ITV and then on the UKTV-owned channel Watch whereas the fifth series would air first on Watch. The production team were thrilled to be able to produce two additional series since it would allow them to resolve the plotlines of the previous series and move Primeval further. The fourth and fifth series had a combined budget of £15 million.

Writing and development

Although most of the cast of the third series were announced as returning for the fourth and fifth series, the production needed to cast several new characters; the third series had seen the departure of protagonists Nick Cutter (Douglas Henshall) and Jenny Lewis (Lucy Brown) as well as antagonist Helen Cutter (Juliet Aubrey). Though new main characters were added in the third series to replace them, not all actors were able to return for the fourth series; Laila Rouass, who played new addition Sarah Page, announced her exit due to being a single parent and not being able to commit to the lengthy filming period of the two new series. In the context of the series, her absence was explained by her character having died offscreen. Jason Flemyng, who played the new lead character Danny Quinn, was also unable to return in a large capacity on account of a movie role and ultimately only made an appearance in the final episode of the fourth series. Much of the fourth series as envisioned prior to the cancellation would have revolved around Danny Quinn's relationships with the other characters which meant that a lot had to be reworked. The ending to Quinn's storyline as shown in the last episode of the fourth series was the original intended ending for his character but it would probably not have transpired as quickly if Flemyng had been able to star in the entire series.

In addition to Danny Quinn, the third series also left Connor Temple (Andrew-Lee Potts) and Abby Maitland (Hannah Spearritt) stranded in the past. Though Potts and Maitland reappeared in the first episode of the fourth series and continued to be part of the main cast thereafter, they were, alongside Ben Miller, the only main cast members to remain from the first series. Although her character was killed off at the end of the previous series, Juliet Aubrey still expressed a wish to return to Primeval during the pre-production of the fourth series. Fans speculated that Nick Cutter would make a return, despite also having been killed off, but Douglas Henshall denied the rumours.

The new cast members Ciarán McMenamin, Ruth Kearney and Alexander Siddig were announced on the ITV website on 8 April 2010. The disappearance of Danny Quinn at the end of the third series and Flemyng's inability to come back for a full series necessitated the introduction of a new ARC team leader. His replacement was Matt Anderson, played by Ciarán McMenamin. McMenamin had previously worked together with the Primeval co-creator Adrian Hodges on the 1999 film David Copperfield. McMenamin was approached by the production team for the role and was eager at the opportunity since it was something different from his usual roles in realistic dramas and period pieces. McMenamin was also particularly thrilled to work together with Ben Miller, who had been a hero of his since watching early episodes of Armstrong and Miller in the 1990s. Matt Anderson was written to be a quite mysterious character, having a hidden agenda of his own and combining elements of both Nick and Helen Cutter.

The third series had seen Ben Miller's James Lester battling with his rival Christine Johnson (played by Miller's then wife Belinda Stewart-Wilson), a storyline and dynamic that both Miller and the producers had felt was very successful and engaging. As a result of wanting to keep the element of Lester not being fully in charge, the producers introduced the new character Philip Burton (Alexander Siddig); a technology mogul who due to his funding has partial control over the ARC and as a result has much to say about what goes on. Siddig was approached about Primeval by Adrian Hodges, whom he knew through yearly Sunday lunches at a mutual friend's house. Philip Burton was as an antagonist initially envisioned as a "problem child"-type character who was relatively nice but caused trouble out of greed and ambition rather than maliciousness; his growing interest in the anomalies was to be based on ideas of scientific exploitation rather than a desire to protect the public. The character grew more and more complex as the result of Siddig's suggestions and conversations with the directors while on set. A new set was created for the ARC to reflect the organisation having received a large upgrade and major increase in funding by Burton.

The new character Jess Parker (Ruth Kearney) was written to fill a role that had never been the job of any particular character previously, monitoring screens that indicate anomaly activity and sending the other members of the team out on missions as a sort of Mission Control. Kearney likened her character to Connor Temple in the first series in that Jess was very excitable and enjoyed learning, though noted that she grows more casual and cool over the course of the series.

Captain Becker (Ben Mansfield) was introduced in the third series mainly as a replacement of the military figure Tom Ryan (Mark Wakeling), who was killed off at the end of the first series. In the fourth series, the producers spent time putting Becker in the spotlight more and developing his character beyond that of Ryan's in the first series and properly cementing him as a member of the team. Becker in the fourth series was written to be more mature and as having reached a more senior position in the team; despite joining only during the third series, he was at the start of the fourth series as a result of all the departures and temporal disappearances the longest-serving member of the ARC team other than James Lester. Becker was also written to be remorseful and more careful due to feeling that he was partly to blame for the great losses suffered by the team. Time was also spent on developing the other returning characters further; Connor Temple (Andrew-Lee Potts) and Abby Maitland (Hannah Spearritt) were at last made a couple after a long "will-they-won't-they" relationship and the two were, due to having been stranded in the past for a year, written to be a stronger unit together and as having picked up new skills. Connor was consciously written to begin to become more like his former mentor Nick Cutter.
