Julian Alexander Kitchener-Fellowes (born August 17, 1949), known as Julian Fellowes, was an actor for over twenty years before winning the Academy Award for Writing Original Screenplay in 2001 for Gosford Park.

He often played the part of Kilwillie in the television series Monarch of the Glen.

His novel Snobs was published in 2004. It focused on the social nuances of the upper class and concerned the marriage of an upper-middle class girl, Edith Lavery – the daughter of an accountant and socially aspiring mother – to Charles, Earl Broughton – the son of the Marquess of Uckfield. Fellowes himself comes from the “bottom end of the gentry”, as he has described it, and drew on his inside knowledge of the aristocracy to paint an intricate portrayal of the behaviour and snobbery of the upper class.
