Some drunken actors perform (5)
I believe the answer is:
enact
'perform' is the definition.
(I've seen this before)
'some drunken actors' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ENACT' can be found hidden inside 'drunken actors'.
(Other definitions for enact that I've seen before include "Ordain" , "Establish by statute" , "Establish by law - perform" , "Pass into law" , "Present" .)
