Film-maker seems oddly wrapped up in film music (8)
I believe the answer is:
scorsese
'film-maker' is the definition.
'seems oddly wrapped up in film music' is the wordplay.
'oddly' indicates alternate letters.
'wrapped up in' indicates putting letters inside.
'film music' becomes 'score'.
The alternating letters of 'seems' are 'ses'.
'ses' placed inside 'score' is 'SCORSESE'.
(Other definitions for scorsese that I've seen before include "Martin . . . . . . . ., film-maker" , "Hit (by an idea)" , "Martin -, US film director (Taxi Driver)" , "Martin ___, director of Goodfellas and Raging Bull" .)
