'Jaume Balaguero' came up with the idea for the story after seeing an early 20th century medical photo of a young girl with osteogenesis imperfecta.
Bearwood College in Reading, England was used as the exterior location for the Mercy Falls Children's Hospital.
There is a brief exterior shot looking down a street of shops on a hill and out to sea. This street is Union Street in Ryde on the Isle of Wight.
