シドニー・ポワチエ
Dual nationals holding a Commonwealth citizenship that recognise the British monarch as head of state are entitled to use the styling. Common usage varies from country to country: for instance, dual Bahamian-American citizen Sidney Poitier, knighted in 1974, is often styled 'Sir Sidney Poitier', particularly in connection with his official ambassadorial duties, although he himself rarely employs the title.
