Actors in rep he reviewed like dancing (13)
I believe the answer is:
terpsichorean
'dancing' is the definition.
(I've seen this before)
'actors in rep he reviewed' is the wordplay.
'reviewed' indicates an anagram (To look at again and re view).
'actors'+'in'+'rep'+'he'='actorsinrephe'
'actorsinrephe' is an anagram of 'TERPSICHOREAN'.
'like' is the link.
(Other definitions for terpsichorean that I've seen before include "Related to dancing - chain store rep (anag)" , "Relating to dancing" , "become a dancer" , "of dance numbers" .)
