No Oscar for 1993 film featuring special actor … (8)
I believe the answer is:
thespian
'actor' is the definition.
('thespian' can be a synonym of 'actor')
'no oscar for 1993 film featuring special' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'n' (common abbreviation) and 'n' is found within the answer.
'special' could be 'sp' and 'sp' is found within the answer.
This explanation may well be incorrect...
(Other definitions for thespian that I've seen before include "stage performer" , "Relating to the theatre" , "Tragic actor" , "Player" , "Actor - neat hips (anag)" .)
