Input: Consider Input: Passage: Chibnall suggested including a "bonkers" gang of characters picked from around time and space. He felt that Doctor Who could have "collisions of characters that no other show in the world can do", and that it was about finding a "disparate" group of characters who would "bounce" off each other. Nefertiti's decision not to return to her own time fits in with the historical record, as the date and cause of her death are unknown. Chibnall asked to introduce Rory's father, as Amy and Rory would be leaving in four episodes and Rory's family life had not been explored yet. Mark Williams who played Rory's father previously appeared in the Fifth Doctor audio adventure The Eternal Summer. Rupert Graves, who played an Edwardian hunter in this episode, previously worked with Moffat on the BBC series Sherlock. David Bradley's character, Solomon, was modelled on a "well-known nightclub owner with long hair". Chibnall described him as "half businessman, half Somali pirate". Bradley and Williams had previously worked together on the Harry Potter film franchise. Bradley was later cast as the First Doctor William Hartnell for the 50th anniversary documentary drama An Adventure in Space and Time. Comedy duo Mitchell and Webb provided the voices of Solomon's two robots; executive producer Caroline Skinner called the casting choice "perfect". Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song".

Input: Consider Input: Passage: Steinman provided lyrics for Andrew Lloyd Webber's musical Whistle Down the Wind, which opened in Washington, D.C. in December 1996. However, it received poor reviews and the Broadway run, scheduled for the following April, was cancelled. A reworked and more successful West End production opened at the Aldwych Theatre on July 1, 1998. In addition to a full-length cast album for the London production, an album was released of well-known performers singing pop versions of the songs from the show. This album was produced by Steinman, as usual with Steven Rinkoff. Those performers include Tom Jones, Tina Arena, Boyzone, Elaine Paige, Donny Osmond, The Everly Brothers, Meat Loaf, Boy George, Sounds of Blackness, Bonnie Tyler, Michael Ball, and Lottie Mayor. One track, "No Matter What" performed by Boyzone, reached the peak position on the pop charts in many countries. The same track appeared on a Boyzone album and their greatest hits album. As of 2019, Boyzone's 1998 recording of "No Matter What" is the most recent new song or project written at least in part by Steinman, or to contain any new work of his at all, to achieve major, chart-topping success. The track "Whistle Down the Wind", performed by Tina Arena, from the same album, also had some chart success. There was also a single released in the U.K., for charity, of children from Red Hill Primary School and Sylvia Young Theatre School performing "When Children Rule The World". The singers were called the "Red Hill Children", and the single peaked at #40 on the U.K. singles charts.
