Doctor absorbed by couple's animated film (5)
I believe the answer is:
dumbo
'animated film' is the definition.
(I've seen this before)
'doctor absorbed by couple's' is the wordplay.
'doctor' becomes 'MB' (Bachelor of Medicine, Medicinae Baccalaureus).
'absorbed by' indicates putting letters inside.
'couple' becomes 'duo' (two people).
'mb' inserted within 'duo' is 'DUMBO'.
(Other definitions for dumbo that I've seen before include "movie classic" , "silly man!" , "animated film" , "two-dimensional character with big ears" , "thick-skinned film star" .)
