Filmed under cover (8)
I believe the answer is:
screened
I believe this clue is a double definition.
'filmed' is the first definition.
(thesaurus)
'under cover' is the second definition.
(thesaurus)
(Other definitions for screened that I've seen before include "Tested for disease or infection" , "put on TV" , "made available to view" , "Shown in a cinema" , "Involved in selection process" .)
