Director still getting undressed (4)
I believe the answer is:
tati
'director' is the definition.
(actor and director Jacques Tati)
'still getting undressed' is the wordplay.
'still' becomes 'static' (static can mean still or not moving).
'getting undressed' means to look at the middle letters (the word is undressed of its external letters).
The middle letters of 'static' are 'TATI'.
(Other definitions for tati that I've seen before include "Jacques -, Fr. comedian" , "Jacques -- (Monsieur Hulot's Holiday)" , "Jacques ___ , French comic actor and film director, d. 1982" , "Creator of Monsieur Hulot" , "Jacques ----, French filmmaker" .)
