Major The Honourable James Rupert Bellamy (1881 – October 1929) is a fictional character in the ITV period drama Upstairs, Downstairs, that was originally broadcast for five series from 1971 to 1975.

After a few unsuccessful relationships, James marries Hazel Forrest, but their happiness is short-lived due to their disparate backgrounds; she dies in the Spanish flu pandemic of 1918.

James serves in the Great War but is seriously wounded at Passchendaele on the Western Front in 1917 and subsequently never finds a purpose in life or true love.

James is portrayed as going to Eton and then attends the Royal Military Academy Sandhurst, and by 1904 he has been commissioned as a lieutenant in the Life Guards in the British Army.

Elizabeth was due to be presented to the King and Queen by her Aunt Kate (Lady Castleton), but she ran away from the ball.

In about 1908, James, now a Captain, starts an affair with the former house maid Sarah, who is now a music hall singer and who attends Elizabeth's wedding.

When James returns from India in May 1910, he brings home with him a well-meaning, middle-class, Army Veterinarian Major's daughter named Phyllis Kingman, to whom he has become engaged.

[1] In early March 1912, Richard hires a secretary, Hazel Forrest, and James quickly takes an interest in her.

While his parents are away one weekend in April (right before Lady Marjorie's ill-fated trip aboard the Titanic), James insists that Hazel lunch with him in the Dining Room, much to butler Hudson's disapproval.

This, in addition to Major Cochrane-Danby claiming that James and Diana are sleeping together, leads Hazel to flee Somerby with Rose.

By now, James has left the Army and is working for Jardines in London and plans to transfer to India in 1915, until the Great War intervenes.

The often-unfaithful James has grown increasingly fond of Georgina, his stepcousin and father's ward, who arrived to live at Eaton Place right before Christmas in December 1913.

In April 1915, he returns home on leave and during dinner, at which Sir Geoffrey Dillon is present, makes comments about the incompetent running of the war.

Against Georgina's advice, Richard and Hazel take him back to London in a private ambulance (a converted limousine provided by James' maternal grandmother, the old Dowager Duchess of Southwold).

A chance encounter with Diana Newbury, his former flame and wife of his best friend, in May 1923 leads to them staying in a country cottage together for a week.

However, a note left by Diana to Bunny is read earlier than expected and, before they can leave Britain, Richard finds out and insists that James return to London.
