10 Insane Doctor Who Episodes That Almost Happened
4. Most Haunted: Doctor Who Edition
Tom MacRae's televised Doctor Who contributions are a mixed bag. On the one hand, he penned the decent Cybermen two-parter from Series 2, and on the other, he wrote the terrific Series 6 story The Girl Who Waited. As a result, it's hard to know if he really does have that "special sauce", or if he just got lucky with his second (and final) story.
With that in mind, it's a real shame that we never got to see Century House, which could've provided us with a definitive answer.
Another story intended for Series 4, this ghostly tale was set to follow the Doctor as he appears in an episode of Most Haunted, a show that investigates reported cases of paranormal activity. The location was going to be a creepy old house haunted by a spectre called the Red Widow, with Donna watching the episode at home.
This means that Donna wouldn't have been involved in the episode very much, making Century House a "companion-lite" script, and so, when this story was dropped by showrunner Russell T Davies (who was unsatisfied with the concept), it was replaced with another companion-lite episode, the acclaimed Midnight.
