I believe the answer is:

polemist

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

'controversial type' is the definition.
The definition suggests a singular noun which matches the answer.

'european film' is the wordplay.
'european' becomes 'pole' (someone from Poland).
'film' becomes 'mist' (to film over is to mist or fog over).
'pole'+'mist'='POLEMIST'

'of' is the link.

Can you help me to learn more?

(Other definitions for polemist that I've seen before include "One disputes" , "I argue" , "Controversial writer" , "One argues" .)

I've seen this clue in The Guardian.
