Silent comic making you pay attention (6)
I believe the answer is:
listen
'pay attention' is the definition.
(to listen to someone)
'silent comic' is the wordplay.
'comic' is an anagram indicator.
'silent' anagrammed gives 'LISTEN'.
'making you' is the link.
(Other definitions for listen that I've seen before include "16 (anag.)" , "Tinsel (anag.)" , "Harken" , "Attend (to a sound)" , "Be silent in order to hear" .)
