Actor the Spanish catch going north (5)
I believe the answer is:
gable
'actor' is the definition.
(I know that Gable is a actor)
'the spanish catch going north' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'catch' becomes 'bag' (bagging is a kind of catching).
'going north' says the letters should be written backwards.
'el'+'bag'='elbag'
'elbag' reversed gives 'GABLE'.
(Other definitions for gable that I've seen before include "End of a house" , "Filmstar at the side of the house?" , "Old actor" , "Section of wall between roof slopes" , "US actor" .)
