 Davies ' scriptwriting was affected by the development of a head cold and overrunning script constraints ; he was annoyed that he had written " dialogue [ he had ] been dying to write " with a " faint heart " because he would have to cut it . Because he was behind schedule , he was forced to cancel plans to attend Piper 's wedding and almost cancelled plans to celebrate the New Year with his boyfriend . These problems affected his first draft of the Doctor 's conversation with his companions and encounter with Davros ; he dismissed it as " lame shit " which would waste licence @-@ payers ' money , and replaced it with a different version hours later . The conversation features all of the Doctor 's companions simultaneously talking to the Doctor ; Tate , Tennant , and director Graeme Harper made the creative decision to have the Doctor ignore any mention of the Daleks because they thought the Doctor 's joviality in the scene would be otherwise inappropriate . He eventually finished the script at 1am on New Year 's Eve . Cook reviewed the last pages of the script and suggested that the episode should air without a trailer ; Davies agreed by noting that " [ the BBC ] never send out preview discs of the last episode " and that any advertisements for " Journey 's End " could " just show lots of Daleks and a repeat of " I 'm regenerating " [ the Doctor 's last line in the episode before the regeneration process starts ] . The episode was officially submitted on 7 January 2008 : the preparation date for " The Stolen Earth " and " Journey 's End " .
