Carry On Laughing which - by contrast - are broadcast regularly on British television. It is also considered much less successful at transferring the established formula to the small screen than the "Carry On Christmas specials". The series was conceived after the departures of two long-serving "Carry On" contributors: writer Talbot Rothwell and actor Charles Hawtrey. Furthermore, Kenneth Williams declined to appear in the series. Other "Carry On" regulars only appeared in a minority of episodes: Sid James in only the first four, Hattie Jacques in only one; and Bernard Bresslaw appeared only in the second series. In the absence of Rothwell, other
Carry On Behind already made their final "Carry On" film appearances. Chilly spring filming meant the bare trees, muddy fields and icy breath are all quite visible, although the setting is a summer caravanning holiday. A similar dilemma met the cast and crew in "Carry On Camping". The signage in Fred Ramsden's butcher's shop clearly shows that the shop is closing for the Easter holidays, which can occur as early as March. Whilst this film was in production, Bernard Bresslaw and Joan Sims also appeared in "One of Our Dinosaurs Is Missing", another film being made at Pinewood Studios alongside "Carry On Behind".
