An elderly Alberto Granado makes a short appearance at the end of the film.
Document 2: All the Way to the Ocean: All the Way to the Ocean is a 2016 computer animated short film based on the children's book of the same name by Joel Harper. The screenplay was written by Joel Harper, Pete Michels, and Doug Rowell. The film was directed by Doug Rowell and produced by Joel Harper. The film is narrated by American actress Marcia Cross and features the song With My Own Two Hands by Ben Harper (brother of) Joel Harper. This is an alternate version of the original song featuring Jack Johnson and is also featured on the Curious George film soundtrack "Sing-A-Longs and Lullabies for the Film Curious George". The lyrics focus on how changes in the world can come about when a single person decides to take action. The song's popularity in Europe was such that Ben Harper was awarded French "Rolling Stone Magazine"'s "Artist of the Year" (Artiste De L'Année) in 2003. The film also features music by Joel Harper and Burning Spear with their collaboration on the song The Time is Now. The film stars voice-overs by actress and activist Amy Smart and Australian musician Xavier Rudd.
Document 3: The Motorcycle Diaries (film): The Motorcycle Diaries (Spanish: "Diarios de motocicleta" ) is a 2004 biopic about the journey and written memoir of the 23-year-old Ernesto Guevara, who would several years later become internationally known as the iconic Marxist guerrilla commander and revolutionary Che Guevara. The film recounts the 1952 expedition, initially by motorcycle, across South America by Guevara and his friend Alberto Granado. As well as being a road movie, the film is a coming-of-age film; as the adventure, initially centered on youthful hedonism, unfolds, Guevara discovers himself transformed by his observations on the life of the impoverished indigenous peasantry. Through the characters they encounter on their continental trek, Guevara and Granado witness firsthand the injustices that the destitute face and are exposed to people and social classes they would have never encountered otherwise. To their surprise, the road presents to them both a genuine and captivating picture of Latin American identity. As a result, the trip also plants the initial seed of cognitive dissonance and radicalization within Guevara, who ostensibly would later view armed revolution as a way to challenge the continent's endemic economic inequalities and political repression.

Document 11: Che: Rise and Fall: Che Rise and Fall is a documentary film created by Eduardo Montes-Bradley. The film was entirely shot in Cuba at the time Che Guevara’s remains were airlifted from Bolivia to Santa Clara the final resting place. The documentary features the testimonies of Guevara’s comrades-in-arms in Sierra Maestra, Congo and Bolivia, also with Alberto Granado with whom Guevara rode a motorcycle from Argentina on a trip that will end, tragically, sixteen years later in the jungles of Bolivia, an experience that was brought to the big screen on "The Motorcycle Diaries". "Che Rise and Fall" begins with an account of Guevara's death in Bolivia in 1967, and fittingly ends with footage of the return of his remains for interment in a monument in Santa Clara's Revolution Square some 30 years later.
Document 12: Bibliography of works on Che Guevara: Ernesto "Che" Guevara (June 14, 1928 – October 9, 1967), was an Argentine Marxist revolutionary, politician, author, intellectual, physician, military theorist, and guerrilla leader. His life, legacy, and ideas have attracted a great deal of interest from historians, artists, film makers, musicians, and biographers. In reference to the abundance of material, Nobel Prize–winning author Gabriel García Márquez has declared that "it would take a thousand years and a million pages to write Che's biography."
Document 13: Che (2008 film): Che is a two-part 2008 biopic about Argentine Marxist revolutionary Ernesto "Che" Guevara, directed by Steven Soderbergh and starring Benicio del Toro. Rather than follow a standard chronological order, the films offer an oblique series of interspersed moments along the overall timeline. "Part One" is entitled "The Argentine" and focuses on the Cuban Revolution from the landing of Fidel Castro, Guevara, and other revolutionaries in Cuba to their successful toppling of Fulgencio Batista's dictatorship two years later. "Part Two" is entitled "Guerrilla" and focuses on Guevara's attempt to bring revolution to Bolivia and his demise. Both parts are shot in a cinéma vérité style, but each has different approaches to linear narrative, camerawork and the visual look.
Document 14: Legacy of Che Guevara: The legacy of Argentine Marxist revolutionary Che Guevara (June 14, 1928 – October 9, 1967) is constantly evolving in the collective imagination. As a ubiquitous symbol of counterculture worldwide, Guevara is one of the most recognizable and influential revolutionary figures of the twentieth century. However, during his life, and even more since his death, Che has elicited controversy and wildly divergent opinions as to who he was and what he represented. Mostly revered and occasionally reviled, he is passionately characterized along the entire continuum as everything from a heroic defender of the poor, to a cold-hearted executioner. Admired, sanctified, romanticized and derided, his crystallized status as either a brilliant intellectual or a violent ideologue is usually dependent on where one falls along the left and right of the political spectrum. The debate around his legacy is further complicated by the fact that Guevara exists simultaneously as several different entities, both literal man and global emblem, leading to disputes between what people contend he did and what he now represents.
Document 15: La Barranca: La Barranca has been a successful ongoing outfit for over a decade. Based in Mexico City, they are led by guitarist and songwriter José Manuel Aguilera, who previously and concurrently worked with Sangre Azteka, Jaguares, Cecilia Toussaint, Steven Brown/Nine Rain (Tuxedomoon), and more. He has an unusually economical style of playing that concentrates on great rhythms, superb tone, and very melodic solos. After the original lineup—Aguilera, Federico Fong (bass), Alfonso Andre (drums), all of whom were guest members of Jaguares with former Caifanes frontman Saúl Hernández—went its separate ways, a second version of the band included Santa Sabina guitar virtuoso Alex Otaola and the extremely flexible rhythm section of brothers Jose María ("Chema") and Alonso Arreola. The band's sound effortlessly moves from flat out rock to fusion-ish jamming and passes through a kind of Mexican folk influence along the way. Aguilera is a good singer with a talent for finding simple melodies amidst rather complex songs. On "El Fluir" the band decided to record live and to cut back on the keyboard and programmed additions to their music. Surprisingly, the result was not an over-the-top jamfest but rather a very tightly arranged set of songs that hinted at the overwhelming power they could possess in concert. The two guitar interplay between Aguilera and Otaola was highly impressive as they explored all forms of playing together and against one another (with Otaola pulling all sorts of radical sounds out of his guitar). "El Fluir" was their first US release since "Tempestad" in 1998. This edition was further sweetened by the inclusion of a previously unreleased bonus track and a video for the first single "Pare de Sufrir."
