As you might remember from my thoughts on season 1 of the show, Blake’s 7 was the brainchild of Terry Nation and he ended up writing the entire first season all on his ownsome, establishing the series’ unusually dark tone for a 1970s space opera television series along with a beloved cast of core protagonists and recurring enemies. This was actually more than originally planned – the initial intention had been that he’d write the first seven episodes and a two-part finale for season 1, and the remaining four episodes would be written by other hands.
As a result of having to pen more episodes than expected, Nation had to rush it, turning in only a first draft of each script and giving script editor Chris Boucher a very free hand in script revisions, which explains why the first season is a bit shonky in places. (Apparently Bounty was especially badly affected, to the point where on set director Pennant Roberts had to improvise ways to pad out scenes to reach the target running time.)
Clearly, it was time for other hands to get involved, so on season 2 more writers ended up getting involved. In fact, Terry Nation only wrote three episodes for the season – each of which a significant tentpole episode setting up the action for the next third or so of the season – whilst Chris Boucher ended up turning in 4. (By this point Boucher, in his script editor role, had become so conversant with the series continuity that he actually wrote the terminology guide to assist other writers in churning out Blake’s 7-flavoured technobabble.) Let’s see if the additional hands boosted the quality of the series whilst retaining its consistency of tone – or whether they steered it right into a ditch.
