Movie playing to close Horrorthon? Take Possession of the House! (4,2)
I believe the answer is:
move in
'movie playing to close horrorthon? take possession of the house' is the definition.
I can't tell whether this defines the answer.
'movie playing to close horrorthon?' is the wordplay.
'playing' indicates an anagram.
'to close' means one lot of letters go next to another.
'horrorthon?' becomes 'n' (I can't explain this - if you can you should believe this answer much more).
'movie' anagrammed gives 'movei'.
'movei'+'n'='MOVE IN'
Can you help me to learn more?
(Another definition for move in that I've seen is " Take up new home".)
