Filmed by night - it's a chancy business (4,2,3,4)
'chancy business' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'filmed by night it's a' is the wordplay.
'filmed' becomes 'shot' ('shoot' can be a synonym of 'film').
'by' is a charade indicator (letters next to each other).
'night' becomes 'dark' (synonyms).
'it's a' becomes 'inthe' (I can't justify this - if you can you should believe this answer much more).
'dark' put after 'inthe' is 'inthedark'.
'shot'+'inthedark'='SHOT IN THE DARK'
Can you help me to learn more?
(Other definitions for shot in the dark that I've seen before include "Pure guess" , "Blind guess" , "Guess based on little information" , "Wild guess" .)
'chancy business' is the definition.
(I've seen this before)
'filmed by night it's a' is the wordplay.
I cannot quite understand how this works, but
'by' could be 'of' and 'of' is found in the answer.
'a' is present in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
