Director seems oddly overwhelmed by result (8)
I believe the answer is:
scorsese
'director' is the definition.
(Martin Scorsese director)
'seems oddly overwhelmed by result' is the wordplay.
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
'overwhelmed by' is an insertion indicator (inserted letters get absorbed or overwhelmed).
'result' becomes 'score' (I've seen this before).
The alternating letters of 'seems' are 'ses'.
'ses' going into 'score' is 'SCORSESE'.
(Other definitions for scorsese that I've seen before include "Martin -, US film director (Taxi Driver)" , "Martin . . . . . . . ., film-maker" , "Martin ___, director of Goodfellas and Raging Bull" , "Hit (by an idea)" .)
