Repeated in The Adventurer and others (5)
I believe the answer is:
reran
'repeated' is the definition.
(I've seen this before)
'in the adventurer and others' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RERAN' is hidden in the letters of 'adventurer and others'.
(Other definitions for reran that I've seen before include "repeated" , "Broadcast again" , "tipped from seminar erelong" , "Showed (a film) again" .)
