 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".
