Calling direction to leading actresses from Dynasty (6)
I believe the answer is:
naming
'calling' is the definition.
('name' can be a synonym of 'call')
'direction to leading actresses from dynasty' is the wordplay.
'direction' becomes 'n' (N is an example**).
'to leading' says to take the initial letters.
'from' is a charade indicator (letters next to each other).
'dynasty' becomes 'ming' (I've seen this before).
The initial letter of 'actresses' is 'a'.
'n'+'a'+'ming'='NAMING'
(Other definitions for naming that I've seen before include "Allotting term to" , "Identifying; mentioning" , "Christening" , "Conferring appellation on" , "Calling" .)
