Chicken sandwich, US style? That'll get one animated (6,9)

I believe the answer is:

yellow submarine

'one animated' is the definition.
(animated Beatles film)

'chicken sandwich us style?' is the wordplay.
'chicken' becomes 'yellow' (as in cowardly).
'sandwich us style?' becomes 'submarine' (type of sandwich size in the US).
'yellow'+'submarine'='YELLOW SUBMARINE'

'that'll get' acts as a link.

(Another definition for yellow submarine that I've seen is " Beatles' film".)

I've seen this clue in The Guardian.
