 Although the series is a continuation of the one-off play, a number of casting and character changes were made.The character of Sergeant Wilding changes name to Sergeant Cryer, and was recast with Eric Richard replacing Peter Dean.Since the transmission of "Woodentop", Dean had secured the role of Pete Beale in "EastEnders", following the re-casting of the original choice, Leslie Grantham, as Den Watts.
