I star in a moving production (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
astir
'moving production' is the definition.
'astir' can be an answer for 'moving' (I've seen this before). I am unsure of the 'production' bit.
'i star' is the wordplay.
'i star' anagrams to 'ASTIR'.
However, I am unsure how the anagram is indicated.
'in a' is the link.
Can you help me to learn more?
(Other definitions for astir that I've seen before include "Up and about -- is art (anag)" , "abroad" , "Busy" , "Moving; out of bed" , "Excitedly moving" .)
