There was initial uncertainty over whether a third series would be produced. In an April 2008 interview, Jones said "We never intended to write a second series let alone a third. We don't want it to become predictable. We will see how the Christmas special goes and take it from there." Corden added: "We will write one if we can make it better. We have to be true to ourselves." Corden and Jones completed the final draft of the Christmas Special by September 2008, although they ruled out writing the third series at the time due to pressures of other work, and repeating the wish not to produce a sub-standard script. After the 2008 Christmas special premiere, BBC Three aired a making-of documentary about the special, titled "12 Days of Christmas".
