Film buff beginning to tour continent (8)
I believe the answer is:
fantasia
'film' is the definition.
(I've seen this before)
'buff beginning to tour continent' is the wordplay.
'buff' becomes 'fan' ('fan' can be a synonym of 'buff').
'beginning to' indicates taking the first letters.
'continent' becomes 'asia' (Asia is an example).
The initial letter of 'tour' is 't'.
'fan'+'t'+'asia'='FANTASIA'
(Other definitions for fantasia that I've seen before include "Nineteen-forty Disney cartoon film" , "free-form composition" , "D [Disney] made" , "Disney's 1940 masterpiece" , "Free-form compostion" .)
