The series was created for ABC by Sydney Newman. When Police Surgeon was cancelled, Newman took Hendry and co-star Ingrid Hafner to a new series: The Avengers. It is sometimes mistakenly claimed that The Avengers was a direct sequel to Police Surgeon, with Hendry playing the same character in both. Although there were similarities, this was in fact not the case. This myth has possibly been encouraged because material relating to Police Surgeon is scarce, and that the first episode of The Avengers aired only one month after the final episode of Police Surgeon.
