The second special, Carry On Again Christmas, was shown the following year. Rothwell did not script this episode, but Sid Colin, who had co-written Carry On Spying with Rothwell, wrote the episode with Dave Freeman, who would go on to script Carry On Behind, several episodes of the Carry On Laughing television series, and the 1992 film, Carry On Columbus. Based on the Robert Louis Stephenson story Treasure Island, this episode saw the Carry on debut of Wendy Richard, who would go on to have small roles in Carry On Matron and Carry On Girls.
Although the 1969 special was broadcast in colour, the 1970 special was shown in black and white due to a technicians' strikes that caused Thames television to broadcast all their Christmas shows that year in black and white.
