Stage star with media frenzy (9)
I believe the answer is:
dramatise
'stage' is the definition.
('stage'->'dramatize' is in my internal thesaurus and 'ize'->'ise')
'star with media frenzy' is the wordplay.
'with' means one lot of letters go next to another.
'frenzy' indicates an anagram.
'star'+'media'='starmedia'
'starmedia' anagrammed gives 'DRAMATISE'.
(Other definitions for dramatise that I've seen before include "Overstate" , "Make out to be exciting or important" , "adapt for TV" , "prepare for the stage" .)
