Idris Elba's character's passport is shown ~2min in. It is clearly a dark blue British Passport, including the new image of the British isles as background. The details page however clearly says it was issued on 17th April 2016 (expires 2026). Before Brexit in 2020, all British passports were red EU passports and have been since 1990. It is impossible to have a blue British passport issued in 2016, 4 years before they were released.
