Overview
- Vicky McClure is confirmed to reprise her role as Metropolitan Police explosives officer Lana Washington and is credited as an executive producer on series four.
- Producers filmed series three and four back-to-back over an intensive nine-month shoot to boost production values and maintain creative continuity.
- Writer Chris Brandon has warned the new episodes will intensify danger and tension, declaring that “no one’s safe” as each episode tightens pressure on the team.
- Series four places greater emphasis on Lana’s mental state, including therapy scenes that McClure says were partly improvised to let the character be explored beyond technical bomb-disposal work.
- The show’s future beyond series four remains open: creators declined to rule out a fifth season and say renewal will depend on viewer response and ITV’s commissioning decisions.
