to be distracting. Camille Coduri, who played Jackie, wore a wig for this episode. Some of the conversation between Rose and her father in the car was cut because the car had made the dialogue delivery too "bouncy". Piper was scared of holding the baby. Because the baby is present throughout the majority of the episode, but the number of hours they could work with the infant was limited, an "artificial baby" was used as a placeholder in some scenes. The Reapers went through many designs. Originally, they were supposed to be "men in cowls" based on the Grim Reaper; the final design retains some of this image with its "scythe-like tail". The original design was deemed too similar to creatures seen in "The End of the World", and so were reworked into something more "otherworldly". They were not originally intended to fly. There was also discussion of how much they should resemble animals as opposed to the Grim Reaper; the end result is a mixture of the two approaches. The final design had a "shark quality", bat wings, and a mouth influenced by the praying mantis. Vulture sound effects were used for its screech. The model was made over two months, being finished at the end of February 2005 rather than at the beginning of January as scheduled. The special effects team then had two or three weeks to complete the "40-odd shots" of the completely CGI Reapers in the episode. The episode ended up being more expensive than intended because of the CGI. When time is damaged, one of the effects is that mobile telephones all begin to repeat the message, "Watson, come here, I need you," purportedly Alexander Graham Bell's first words ever spoken over a telephone. However, historical records indicate the words to be "Watson, come here, I want you." The error was not present in Paul Cornell's original script, but crept in at some point during production. Producer Phil Collinson speculated that it was because the line was rerecorded: it was originally recorded by someone who the production team felt put on too false a Scottish accent, and so it was rerecorded by a real Scot.
