There is some confusion about the actresses who played the prisoners in Holloway Prison. In the credits for Episode 1, actresses Katrina Buchanan, Lorraine Carroll, Sue Gifford and Amanda Maylin are credited as playing characters Natasha Alexander, Collette Johnson, Delyth Morgan and Claudia Curran. However in the credits for Episode 5, *all* these names (both the actress and the character names) are credited as "Prisoner".
Dolly tells Ester that she saw Shirley Miller being shot. However in Widows (1983) she was not present at the shooting.
