Star characters in Disney film (5,5)

I believe the answer is:

white dwarf

'star' is the definition.
(white dwarf is a kind of star)

'characters in disney film' is the wordplay.
I cannot quite understand how this works, but
'film' could be 'it' and 'it' is found in the answer.
This may be the basis of clue (or it may be nonsense).

(Another definition for white dwarf that I've seen is " Star".)

I've seen this clue in The Guardian.
