Good-looking lead characters in Carry On movies - everybody loves you! (6)
I believe the answer is:
comely
'good-looking' is the definition.
(I've seen this before)
'lead characters in carry on movies everybody loves you' is the wordplay.
'lead characters in' says to take the initial letters.
The initial letters of 'carry on movies everybody loves you' is 'COMELY'.
(Other definitions for comely that I've seen before include "Archaic word for good-looking, say maidens" , "Very pleasing to the eye, as Dev's maidens perhaps" , "'Very pleasing to the eye, a de Valera maiden perhaps (6)'" , "Pleasing, graceful" , "Attractive" .)
