Guillermo Cabrera Infante, Cuban author, screenwriter, and critic (b. 1929)
Guillermo Cabrera Infante (Spanish pronunciation: [ɡiˈʎeɾmo kaˈβɾeɾa iɱˈfante]; Gibara, 22 April 1929 – 21 February 2005) was a Cuban novelist, essayist, translator, screenwriter, and critic; in the 1950s he used the pseudonym G. Caín, and used Guillermo Cain for the screenplay of the cult classic film Vanishing Point (1971).

A one-time supporter of the politics of Fidel Castro, Cabrera Infante went into exile to London in 1965. He is best known for the novel Tres tristes tigres (literally: "three sad tigers", published in English as Three Trapped Tigers), which has been compared favorably to James Joyce's Ulysses.
