On completion in June, script editor Christopher H. Bidmead found the scripts to be overlong, as well as needing more work to keep them in line with other stories in the series. Therefore, he and director Paul Joyce re-worked the story significantly, including re-writing much of the dialogue. Originally, the script was much more comedic, with Rorvik's crew being given a lot of humorous dialogue, two of the workers being played as a double-act. Executive producer Barry Letts in particular was against this, saying that it was turning the show into pantomime and stated that the crewmen must be played for real. As many of these lines were cut from the script, the few remaining "comedy" lines were to be played straight as well. The scripts were finalised in late August 1980, but were then criticised by Letts, who found them rather confusing. By this time however, there was no more time to rework them further as Bidmead needed to begin work on the following story. Producer John Nathan-Turner too found the story complicated but had not got involved with the story during its scripting stages. Bidmead met with Gallagher with the revised scripts, the latter being none too happy with the extensive changes.
