Disney film buff takes time on continent (8)
I believe the answer is:
fantasia
'disney film' is the definition.
(1940 film)
'buff takes time on continent' is the wordplay.
'buff' becomes 'fan' (eg a film buff is a film fan).
'takes time' becomes 't' (I've seen this in other clues).
'on' means one lot of letters go next to another.
'continent' becomes 'asia' (Asia is an example).
'fan'+'t'+'asia'='FANTASIA'
(Other definitions for fantasia that I've seen before include "Disney's 1940 masterpiece" , "Musical composition of several familiar tunes" , "animated film" , "free-form composition" , "Florid and fanciful composition" .)
