Shoot a film with Loren - not as good as La Dolce Vita (6,4)

'good as la dolce vita' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'shoot a film with loren not' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'film' could be 'm' (Fritz Lang film) and 'm' is present in the answer.
'not' could be 'no' (I've seen this in other clues) and 'no' is found within the answer.
This may be the basis of clue (or it may be nonsense).

'as' is the link.

Can you help me to learn more?
