Katy Manning: Doctor Who 'filming was full on'

11 June 2014 Last updated at 23:59 BST

A Doctor Who story from the early 1970s that was filmed at Dover Castle has been restored to colour for the first time since it was broadcast.

The castle doubled up as a prison for the classic 1971 Mind of Evil story featuring third Doctor, Jon Pertwee.

Katy Manning, who played the Doctor's companion Jo Grant, told BBC South East Today she had very happy memories of the filming, when she returned to the castle for the first time in more than 40 years.
