Obstruct a film director with everything (9)
I believe the answer is:
stonewall
'obstruct' is the definition.
(I know that stonewall is a more specific form of the action obstruct)
'a film director with everything' is the wordplay.
'a film director' becomes 'Stone' (Oliver Stone).
'with' becomes 'w' (short for with).
'everything' becomes 'all' (all things).
'stone'+'w'+'all'='STONEWALL'
(Other definitions for stonewall that I've seen before include "Obstruct by refusing to answer questions" , "delay in parliament" , "Play to defend" , "Hold up progress" , "Engage in delaying tactics - General Jackson?" .)
