Actor Gardner on pitch in movie (6)
I believe the answer is:
avatar
'movie' is the definition.
(I've seen this before)
'actor gardner on pitch' is the wordplay.
I cannot really see how this works, but
'gardner' could be 'ava' (actress Ava Gardner) and 'ava' is located in the answer.
'pitch' could be 'tar' (synonyms) and 'tar' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for avatar that I've seen before include "Manifestation of a deity (Hinduism)" , "A person who seems to embody a particular ideal" , "Computer object representing the user" , "Bodily form of (Hindu) deity" , "Manifestation of a deity; cyberspace icon" .)
