Talk endlessly with composer and film director (9)
I believe the answer is:
spielberg
'film director' is the definition.
'spielberg' can be an answer for 'director' (I have seen 'Director of Jaws' mean 'spielberg' so perhaps 'director' could also mean 'spielberg'). I'm not sure about the 'film' bit.
'talk endlessly with composer' is the wordplay.
'talk endlessly' becomes 'spiel' (spiel can mean a sales pitch or talk. I am not sure about the 'endlessly' bit.).
'with' says to put letters next to each other.
'composer' becomes 'Berg' (p0th Century Austrian composer).
'spiel'+'berg'='SPIELBERG'
'and' is the link.
Can you help me to learn more?
(Other definitions for spielberg that I've seen before include "Schindler's List director" , "Director of Jaws" .)
