My Life: A Spoken Autobiography by Fidel Castro and Ignacio Ramonet was published in Spanish in 2006 ("Fidel Castro: Biografía a dos voces"), and English in 2008.
 The book was written by Ramonet based on more than 100 hours of interviews with Castro.
Brian Stewart is a British playwright.
 He is best known for his play "Castro's Beard" that was first produced by the Deptford players, off-broadway in 2001.
 The New York Times described it as a 'Mordant, irreverent Comedy that was timely and thought-provoking'."
 It was subsequently produced by the Barrington Stage Company in Massachusetts in 2002 and then at the Stages Repertory Theatre, Houston in 2004.
 Following a rehearsed reading at the Arts centre in London in 2005 - with a cast that included David Soul and Timothy West - the play was produced by the Theatre Royal Haymarket, in association with Richard Jordan Productions and the Yvonne Arnaud Theatre, Guildford, and embarked on a number one tour of the UK in 2006 when the name was changed to "Killing Castro".
 The cast included: Edward Hardwicke (Torphy), Clive Mantle (Brawner), Michael Praed (Madison) and Martin Shaw's son, Joe Shaw, as Drake.
 The play which centres on the true plots by the CIA to assassinate Fidel Castro in the 1960s received mixed reviews in the UK.
 It was described by the "Birmingham Mail" as an "acclaimed comedy" which "chronicles the more bizarre of America's attempts to kill the Cuban leader Fidel Castro - including filling his shoes with poison and inventing an exploding cigar."
 The "Daily Telegraph" said "The British dramatist Brian Stewart appears to have got lucky with this intermittently entertaining but rather trite little play about the CIA's plots to bump off Fidel Castro."
.
 Although, Michael Billington of the Guardian was much more complimentary: 'Stewart's weapon is comedy.
 But his argument, that America will stop at nothing in its defiance of international law, is no different from that of Pinter in his Nobel speech.'
.
 The play was published by Josef Weinberger in 2009.
 In 2013, the play was translated into Polish by Karolina Mackiewicz and performed in repertory by the Teatr Polski Szczecin as "Operacja Castro"; the director was Bartłomiej Wysozomirski.
Comandante is a political documentary film by American director Oliver Stone.
 In the film, Stone interviews Cuban leader Fidel Castro on a diverse range of topics.
 Stone and his film crew visited Castro in Cuba for three days in 2002, and the film was released in 2003, having its premiere at the Sundance Film Festival early that year.
The state visit of Fidel Castro to Chile in 1971 was a landmark event both for Chilean internal politics and for the foreign relations of Cuba.
 Castro’s visit occurred as Chile was experiencing political convulsion amidst the presidency of Salvador Allende who had been elected in 1970.
 For Cuba it was the first state visit of Fidel Castro since he visited Moscow in 1964 and served to break the diplomatic isolation the country was subject to in Latin America.
 The state visit was unprecedented as Castro stayed 25 days in the country, travelling it from north to south, and commenting on Chilean politics.
 Upon arrival to each town and city Castro was usually met by crowds of supporters.
 His visit ended up making Salvador Allende uncomfortable and the Chilean right-wing exploiting it to discredit the Unidad Popular government.
Sweet Crude is a documentary film by Sandy Cioffi about Nigeria's oil-rich Niger Delta.
 The film premiered in April 2009 at the Full Frame Documentary Film Festival and has since screened at 30 film festivals around the world and has won numerous awards.
With the 2006–2008 Cuban transfer of presidential duties, the Cuban presidential powers and duties were passed on from President Fidel Castro to the first vice president, his brother Raúl Castro, following Fidel's operation and recovery from an undisclosed digestive illness believed to be diverticulitis.
 Although Raúl Castro exercised the duties of president, Fidel Castro retained the title of President of Cuba, formally the President of the Council of State of Cuba, during this period.
The nation of Cuba under Fidel Castro underwent significant changes that have received much attention.
 Fidel Castro and his associated group of revolutionaries toppled the ruling government of Fulgencio Batista, forcing Batista out of power on 1 January 1959.
 Having already been an important figure in Cuban culture and society, he went on to serve as 'Prime Minister of Cuba' from 1959 to 1976.
 In 1976, Castro officially became 'President of Cuba'.
 Castro retained the title of president until 2008, when his brother Raúl Castro became president.
 He also served as the First Secretary of the Communist Party of Cuba (1961-2011).
 However, his opinions continued to serve as the foundation of Cuban governance.
Looking for Fidel is a documentary film by Oliver Stone, released in 2004.
 It is a follow-up to his 2003 documentary "Comandante" and likewise consists of interviews with the Cuban leader Fidel Castro.
 This time, interviews of some Cuban political dissidents are included as well.
 The film specifically deals with the 2003 crackdown on dissidents in Cuba, and the execution of three men who attempted to hijack a ferry to the United States.
Pennsylvania Grade Crude Oil is a type of sweet crude oil (sweet crude oil), found primarily in the Appalachian basin in the Marcellus Formation in the states of New York, Pennsylvania, Ohio, and West Virginia, and takes its name for the state of Pennsylvania, where it was first extracted in 1859 from the Drake Well.
 The area's Pennsylvania Grade Crude Oil has superior qualities and is free of asphaltic constituents, contains only trace amounts of sulfur and nitrogen, and has excellent characteristics for refining into lubricants.
 The success of drilling for oil at this well led to "an international search for petroleum, and in many ways eventually changed the way we live."
 There is archaeological evidence that Native Americans harvested "the oil for medicinal purposes by digging small pits around active seeps and lining them with wood" at least as far back as 1410 AD.
 European settlers skimmed the "oil from the seeps and using the petroleum as a source of lamp fuel and machinery lubrication."
The early life of Cuban revolutionary and politician Fidel Castro, born Lina Castro, spans the first 26 years of his life, from 1926 to 1952.
 Born in Birán, Oriente Province, Castro was the illegitimate son of Ángel Castro y Argiz, a wealthy farmer and landowner, and his mistress Lina Ruz González.
 First educated by a tutor in Santiago de Cuba, Fidel Castro then attended two boarding schools before being sent to El Colegio de Belén, a school run by Jesuits in Havana.
 In 1945 he began studying law at the University of Havana, where he first became politically conscious, becoming a staunch anti-imperialist and critic of United States involvement in the Caribbean.
 Involved in student politics, he was affiliated to Eduardo Chibás and his Partido Ortodoxo, achieving publicity as a vocal critic of the pro-U.S. administration of President Ramón Grau and his Partido Auténtico.
