bigamist

I'm a little stuck... Click here to teach me more about this clue!

'partner in crime' is the definition.
'bigamist' can be an answer for 'partner' (bigamist is a kind of partner). I'm unsure of the 'in crime' bit.

'great film about a' is the wordplay.
'great' becomes 'big' (synonyms).
'film' becomes 'mist' (to film over is to mist or fog over).
'about' is a charade indicator (letters next to each other).
'mist' put after 'a' is 'amist'.
'big'+'amist'='BIGAMIST'

Can you help me to learn more?

(Other definitions for bigamist that I've seen before include "lawbreaking union member" , "One who marries more than once illegally" , "Person who commits crime of marrying while still married to another" , "Marital cheat" , "One marries while already legally married to another" .)

I've seen this clue in The Sunday Times.
