Game of Thrones revival immediately starts with bottle hunt (7,7)
I believe the answer is:
trivial pursuit
'game' is the definition.
(I know that Trivial Pursuit is a board game)
'bottle hunt' is the wordplay.
'bottle' becomes 'trivial' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hunt' becomes 'pursuit' (synonyms).
'trivial'+'pursuit'='TRIVIAL PURSUIT'
'of thrones revival immediately starts with' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
(Another definition for trivial pursuit that I've seen is " Popular board game".)
