I believe the answer is:
attraction
'pulling power' is the definition.
(thesaurus)
'fantastic actor titan' is the wordplay.
'fantastic' indicates an anagram.
'actor'+'titan'='actortitan'
'actortitan' is an anagram of 'ATTRACTION'.
'with' is the link.
(Other definitions for attraction that I've seen before include "Charm" , "Appeal" , "Pull" , "Popular building/place" , "Draw, allure" .)
