Enough dollars to make a movie (7)
I believe the answer is:
fistful
'enough' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Maybe you can see an association between them that I don't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fistful that I've seen before include "A -- of Dollars (Clint Eastwood)" , "As much as can be held in the hand" , "A -- of Dollars (film)" , "amount of dollars?" , "it should be within one's grasp" .)
