Psychiatrist to finish shooting film? (6-4)

Ross

I believe the answer is:

shrink-wrap

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

'film?' is the definition.
Both the answer and definition are verbs in their base form.
Perhaps you can see a link between them that I can't see?

'psychiatrist to finish shooting' is the wordplay.
'psychiatrist' becomes 'shrink' (informal term for a psychiatrist).
'to finish shooting' becomes 'wrap' (I've seen this in another clue).
'shrink'+'wrap'='SHRINK-WRAP'

Can you help me to learn more?

(Other definitions for shrink-wrap that I've seen before include "Tightly package in flexible plastic" , "Seal tightly with plastic film" , "Cover in plastic" .)

I've seen this clue in The Times.
