These were ‘Boutique’ reversions. The idea was to do more than just change the voice over. All the shows were re-structured so as to improve the dramatic tension across a UK broadcast formate (3 ad breaks with varying part durations). This often meant that many scenes needed tweaking or changing in the edit. Also The voice over wasn’t just reduced but re written, which also impacted on how individually scene payed out. Thus it was rare for any scene or story to be left untouched.
Series teasers, episode teasers, part teasers, and ‘next time on…’ teasers were also edited from scratch.
