If you direct badly, Alan Smithee will get this. (6)
I believe the answer is:
credit
'get this' is the definition.
The definition suggests a singular noun which matches the answer.
'if you direct badly alan smithee' is the wordplay.
'direct' anagrams to 'CREDIT'.
However, I'm unsure how the anagram is indicated.
'will' acts as a link.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "'Give ...... where ...... is due'" , "Time given to pay for goods" , "Belief; tick" , "Side of an account for payments in" , "Arrangement for deferred payment" .)
