Princess Kate's brother James Middleton has said that he believes his sister's dog, Orla, is doing her part to support the royal during her battle with cancer.

Middleton told The Times that after his Bible reading at the wedding was broadcast, an American production company contacted him to offer a starring role in his own film, opening bid $1million. Middleton added in his book of the invitation: “They even ventured that members of my wider family might like to take part.”
