Talk of a singular shark movie? (3)

Ross

I believe the answer is:

jaw

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

'talk' is the definition.
(jawing is a kind of talking)

'a singular shark movie?' is the wordplay.
'a singular shark' becomes 'ja' (I can't justify this - if you can you should give a lot more credence to this answer).
'movie?' becomes 'W' (W, film about George W Bush).
'ja'+'w'='JAW'

'of' is the link.

Can you help me to learn more?

(Other definitions for jaw that I've seen before include "Chin bone" , "Gossip" , "Part of skull" , "Natter - mandible" , "It frames the mouth and holds the teeth" .)
