Historical period drama is a film genre in which stories are based on historical events and famous persons.
 Some historical dramas attempt to accurately portray a historical event or biography, to the degree that the available historical research will allow.
 Other historical dramas are fictionalised tales that are based on an actual person and their deeds.
Egaro, the Immortal Eleven is a 2011 Bengali sports film based on a historical event.
 It was directed by debutant director Arun Roy.
 The film is based on the historical events leading to a football match between Mohun Bagan and East Yorkshire Regiment on 29 July 1911, a time when India was under the British rule.
 This was the first time when Mohun Bagan, or any native team won the IFA Shield.
 The film commemorated that event in its centenary year, i.e., 2011.
The 49th Cousin is a play by Florence Lowe and Caroline Francke.
 The work premiered on Broadway at the Ambassador Theatre on October 26, 1960 and closed after 102 performances on January 21, 1961.

 It is Europe's biggest historical event.
History vs. Hollywood was a television show on the History Channel in the United States.
 On the show, experts are interviewed on the historical accuracy of a film that is based on a historical event.
 For example, the movie "The Last Samurai" was featured in one episode in which military historian Geoffrey Wawro, professor of history at the University of North Texas, and director of the university's Barsanti Military History Center, compared the movie with the actual events (December 2003).
 On the show the expert guests discuss the factual accuracy of the film as well as the everyday objects that a person of the particular time period would have seen.
 In some episodes an expert or the host will go on a journey to the actual historical sites depicted in the film, or interview someone who witnessed the event firsthand.
 In each of the more than dozen episodes both expert guests and filmmakers will discuss the historical accuracy of the film dramatized.
Fat Man and Little Boy (a.k.a. Shadow Makers in the UK) is a 1989 film that reenacts the Manhattan Project, the secret Allied endeavor to develop the first nuclear weapons during World War II.
 The film is named after the weapons "Little Boy" and "Fat Man" that were detonated over Hiroshima and Nagasaki, respectively.
 The code names, originally Fat Man and Thin Man, were drawn from characters in the works of Dashiell Hammett.
 However, there's a possible secondary allusion to stout project director Gen. Leslie Groves and the slim scientific director, Dr. J. Robert Oppenheimer.
 The film focuses much attention on the frequently strained relationship between the two men.

The We Were There books are a series of historical novels written for children.
 The series consists of 36 titles, first released between 1955 and 1963 by Grosset & Dunlap.

 The books were written by a number of different authors, each writing from one to seven of the books; the authors included Benjamin Appel, Jim Kjelgaard, Earl Schenck Miers, William O. Steele, and others.
 Each book's byline also lists a separate "historical consultant," who was a specialist in the historic topic covered by that particular book.
 The historical consultants were typically college professors or, in the case of war-related stories, retired military officers; among the more noteworthy consultants for the series were the historians Bruce Catton, Walter Prescott Webb and A. B. Guthrie, Jr..
 The books are illustrated with black-and-white line art, with color drawings on the dust jacket.
