Jude Law demonstrated his chivalrous manners during an interview when a reporter fell of her chair.

After the incident happened when the embarrassed reporter was left lying on the floor, Jude kindly offered water and laughed along.

Law was promoting new film Anna Karenina and after the pair had managed to suppress all giggles, he admitted to being "immensely proud of the movie."

Keira Knightley plays the protagonist in Tom Stoppard's new adaptation of Leo Tolstoy's epic.

The Russian love story was directed by Joe Wright and also stars Aaron Taylor-Johnson.

Anna Karenina opens in cinemas on 7 September.
