However, Ray was contracted to ABC (despite being unused by them), who distributed the Carry On films to cinemas. Unhappy seeing one of their contracted actors in a rival production, they threatened to stop distribution, so Peter Rogers reluctantly dropped him from the films and replaced him with Sid James, thus beginning James's 19-film long membership of the Carry On team.
