M. Hulot's creator (4)
I believe the answer is:
tati
'm hulot's creator' is the definition.
(Jacques Tati created Monsieur Hulot)
This is the entire clue.
(Other definitions for tati that I've seen before include "Jacques -, Fr. comedian" , "Jacques -- (Monsieur Hulot's Holiday)" , "Creator of Monsieur Hulot" , "Jacques ----, French filmmaker" , "Jacques ___ , French comic actor and film director, d. 1982" .)
