When Benedict Cumberbatch saved Keira Knightley from an embarrassing moment

Benedict-Cumberbatch-Keira-KnightleyLondon, Sep 18 : Benedict Cumberbatch recently defended Keira Knightley during a joint interview when the interviewer told her that she looked tired.

David Poland told the 29-year-old actress that she appeared "a little worn out," to which the 'Sherlock Holmes' actor responded that it was not a nice thing to say to one of the most beautiful women on the planet, the Daily Express reported.

The 'Atonement' actress, who was obviously annoyed with the question, followed him and said "f*** you!" to Poland.

However, Knightley later on explained that it was probably because she was really hungry.

The pair was promoting their new film 'The Imitation Game,' which is a historical thriller film about British mathematician, logician, cryptanalyst and computer scientist Alan Turing. (ANI)
