Managed to stop one director touching up another (9)
I believe the answer is:
tarantino
'another' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'managed to stop one director touching up' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'to stop' is an insertion indicator.
'one director' becomes 'Tati' (actor and director Jacques Tati).
'touching' becomes 'on'.
'up' is a reversal indicator (in down clue: letters go upwards).
'on' backwards is 'no'.
'ran' inserted within 'tati' is 'taranti'.
'taranti'+'no'='TARANTINO'
(Other definitions for tarantino that I've seen before include "Quentin -, American film director" , "Who in tarnation is this US film-maker?" , "Quentin -, US director" , "He makes films" , "Quentin ... film maker" .)
