Washington, Apr 10 : Hollywood actress Penelope Cruz has revealed that she was left baffled while filming ‘Elegy’ with her co-actor Sir Ben Kingsley, as she didn’t know how to address him.

The ‘Vanilla Sky’ actress said that she was baffled when she was asked to refer to him with his full name.

Thus, she tried to find ways to avoid saying his name only in a bid to be more comfortable.

"Somebody told me at the beginning, ''You have to call him Sir Ben.'' And I asked, ''Who said that?'' So on the first day I decided never to say his name and to see what came out naturally. I would say ''Excuse me,'' or ''Hi,'' or something but not his name. Then the ''Sir'' just came out. After that I couldn''t call him anything else,” Contactmusic quoted her as saying. (ANI)
