2012 Ben Affleck thriller (4)
I believe the answer is:
argo
'2012 ben affleck thriller' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for argo that I've seen before include "Jason's boat" , "Ship used by Jason in his search for the Golden Fleece" , "Ship involved in the quest for the Golden Fleece" , "Constellation; ship" , "Mythological ship" .)
