Question: Which tribe was Chief Blackfish the Chief of? Passage:Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.

Question: How many films has the actor who was in negotiations to play The Rooms script supervisor, Sandy Schklair starred in? Passage:In June 2014, James Franco's younger brother, Dave Franco, informally announced at a midnight showing of The Room that he had been cast in the co-starring role of Greg Sestero. Wiseau praised the decision in a Q&A session. The film is the first collaboration of James and brother Dave, as the younger Franco has said that he had sought different projects deliberately, specifying in an interview at the Toronto International Film Festival, "I didn't want people to think I was riding his coattails." As New Line Cinema sought to acquire The Disaster Artist in October 2015, one of the film's producers, and frequent Franco collaborator, Seth Rogen, was in negotiations to play The Rooms script supervisor, Sandy Schklair. Schklair expressed concern over the film's portrayal of him, as Rogen did not pursue contact with him, despite his offers to sit down and discuss the film. The remainder of the principal cast were revealed in the days prior to the beginning of filming, in early December 2015: Josh Hutcherson plays Philip Haldiman, Ari Graynor as Juliette Danielle, Jacki Weaver as Carolyn Minnott, Hannibal Buress as Bill Meur, Andrew Santino as Scott Holmes, and Zac Efron as Dan Janjigian. Dave Franco's wife, Alison Brie, joined the cast in the role of Sestero's then-girlfriend, Amber, and Sharon Stone was later announced to have been cast as Hollywood talent agent Iris Burton. Sestero stated in January 2016 that Bryan Cranston had been cast in the film in an undisclosed role. In November 2016, he was revealed to be playing himself during his time working on Malcolm in the Middle.

Question: In what year was the royal house's name change? Passage:The programme explores the lives of King George V and Queen Mary, and their attempts at modernising the British Monarchy in response to the massive social changes during and following World War I. The first episode recalls how, fearing anti-German sentiment, the royal house name was changed by King George from the House of Saxe-Coburg and Gotha to the House of Windsor. The series also examines the personal lives of the couple, delving into their relationships with their children, and with each other. The marriage between George and Mary was an arranged marriage, occurring only because Prince Albert Victor, George's brother and Mary's original fiancé, died from influenza. George V is presented in the series as a disciplinarian, who strictly punished his children, but was known to be much more loving to his granddaughter, Queen Elizabeth II.
