Show runs into new scene (6)
I believe the answer is:
screen
'show' is the definition.
(screening is a kind of showing)
'runs into new scene' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'into' indicates putting letters inside.
'new' indicates an anagram.
'scene' anagrammed gives 'sceen'.
'r' placed into 'sceen' is 'SCREEN'.
(Other definitions for screen that I've seen before include "Room divider" , "Blind - hide from view" , "Flat surface onto which images are projected" , "TV surface" , "Censer (anag.)" .)
