Deborah's king of cinema somewhat conciliatory, ultimately (3)

I believe the answer is:

yul

'deborah's king of cinema' is the definition.
(The King and I stars Deborah Kerr and Yul Brynner)

'somewhat conciliatory ultimately' is the wordplay.
'somewhat' indicates a hidden word.
'YUL' is hidden within 'conciliatory ultimately'.

I've seen this clue in The Guardian.
