Follow That Camel (1966)

Or ‘Carry On Follow That Camel’ according to everyone and everything except the titles.
Phil Silvers gets the guest lead, but the results are patchy. Frankly, we have our team now and we like them as they are; guest stars are fine, but don’t try to give them the whole show. (In truth, Silvers is not on top form even if the script he is given would allow him to be; Williams in his diaries bemoans his unprofessionalism and constantly refers to him as ‘she’. “There seems to be no respite from this kind of man,” he writes. “You mention the county of Kent and he says ‘O! You Kent do that!’ and you’re supposed to fall about.”)
