Hollywood director left bigger screens (6)
I believe the answer is:
wilder
'hollywood director left bigger screens' is the definition.
I can't tell whether this definition defines the answer.
'left bigger screens' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is found within the answer.
The remaining letters 'wider' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for wilder that I've seen before include "More primitive" , "Billy --, US film director and screenwriter" , "American dramatist" , "Less conventional" .)
