County viewed in cinema, Yorkshire (4)
I believe the answer is:
mayo
'county' is the definition.
(county of Ireland)
'viewed in cinema yorkshire' is the wordplay.
'viewed in' indicates the answer is hidden within the clue.
'MAYO' can be found hidden inside 'cinema yorkshire'.
(Other definitions for mayo that I've seen before include "Thick creamy dressing" , "Salad dressing (informal)" , "Eg, Braeburn or Cox" , "Irish county -- salad cream" , "Ir. county; salad dressing" .)
