Talking right through the film! (5,5)

I believe the answer is:

sound track

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

'film' is the definition.
(thesaurus)

'talking right through' is the wordplay.
'talking' becomes 'sound' (synonyms).
'right through' becomes 'track' (I can't justify this - if you can you should believe this answer much more).
'sound'+'track'='SOUND-TRACK'

'the' is the link.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
