Cinema cancelled "Earth Mouse" openings (3,5)
I believe the answer is:
art house
'cinema' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for art house that I've seen before include "Independent cinema" , "Sort of cinema" , "pictures" , "Non-mainstream cinema" , "Up-market cinema" .)
