Film star born in storm (5)
I believe the answer is:
gable
'film star' is the definition.
(I've seen this before)
'born in storm' is the wordplay.
'born' becomes 'b' (abbreviation next to the year of someone's birth).
'in' is an insertion indicator.
'storm' becomes 'gale' (I've seen this before).
'b' inserted inside 'gale' is 'GABLE'.
(Other definitions for gable that I've seen before include "Triangular part of a wall supporting a ridged roof" , "Actor's" , "Triangular brickwork" , "Section of wall between roof slopes" , "Part between sloping sides of a roof" .)
