In the film I made, nothing short-sighted (6)
I believe the answer is:
myopic
'short-sighted' is the definition.
(I've seen this before)
'in the film i made nothing' is the wordplay.
'in the' means one lot of letters goes inside another.
'film i made' becomes 'my pic' (picture can mean a film).
'nothing' becomes 'O' (looks like zero - 0).
'mypic' placed around 'o' is 'MYOPIC'.
(Other definitions for myopic that I've seen before include "Condition of short-sightedness" , "Unable to focus on distant objects" , "Short-sighted" , "Lacking foresight?" , "Imprudent" .)
