Initially blubbing and more blubbing in Disney film (5)
I believe the answer is:
bambi
'disney film' is the definition.
(I've seen this before)
'initially blubbing and more blubbing in' is the wordplay.
'initially' indicates taking the first letters.
The initial letters of 'blubbing and more blubbing in' is 'BAMBI'.
(Other definitions for bambi that I've seen before include "1942 film about a white-tailed deer" , "1942 Disney film" , "Walt Disney's lovable cartoon deer" , "cartoon film" , "7's fawn" .)
