French director contracted to include element of Elizabethan costume (8)

I believe the answer is:
truffaut
'french director' is the definition.
'truffaut' can be an answer for 'director' (Francois Truffaut, 1932-1984). I'm unsure of the 'french' bit.
'contracted to include element of elizabethan costume' is the wordplay.
I cannot really see how this works, but
'element' could be 'ru' (Ru is an example) and 'ru' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for truffaut that I've seen before include "Filmmaker" , "Franois -, French film producer" , "film director" .)
