Film best bowler, perhaps (3,3)
I believe the answer is:
top hat
'film' is the definition.
(1935 film)
'best bowler perhaps' is the wordplay.
'best' becomes 'top' (associated in meaning).
'bowler perhaps' becomes 'hat' (bowler is a kind of hat).
'top'+'hat'='TOP-HAT'
(Other definitions for top hat that I've seen before include "Head gear" , "It's seen with tails" , "1935 Fred Astaire/Ginger Rogers film" , "Upper-class" , "Formal silk headgear" .)
