that: "Eisenstein furthermore agrees that all pictures made or directed by him in Mexico, all negative film and positive prints, and all story and ideas embodied in said Mexican picture, will be the property of Mrs. Sinclair..." A codicil to the contract allowed that the "Soviet Government may have the [finished] film free for showing inside the U.S.S.R." Reportedly, it was verbally clarified that the expectation was for a finished film of about an hour's duration. By 4 December, Eisenstein was traveling to Mexico by train, accompanied by Aleksandrov and Tisse, and also by Mrs. Sinclair's brother, Hunter Kimbrough, a banker with no prior experience in motion picture work, who was to serve as production supervisor. At their departure Eisenstein had not yet determined a direction or subject for his film, and only several months later produced a brief outline of a six-part film; this, he promised, would be developed, in one form or another, into a final plan he would settle on for his project. The title for the project, ¡Que viva México!, was decided on some time later still. Whilst in Mexico, he mixed socially with Frida Kahlo and Diego Rivera; Eisenstein admired these artists and Mexican culture in general, and they inspired him to call his films "moving frescoes". The left-wing U.S. film community eagerly followed his progress within Mexico, as is chronicled within Chris Robe's book Left of Hollywood: Cinema, Modernism, and the Emergence of U.S. Radical Film Culture. Filming was not accomplished in the 3-4 months agreed to in Eisenstein's contract, however, and the Trust was running out of money; and the Soviets' prolonged absence from the USSR led Joseph Stalin to send a telegram to Sinclair expressing the concern that Eisenstein had become a deserter. Under pressure, Eisenstein blamed Mary Sinclair's younger brother, Hunter Kimbrough, who had been sent along to act as a line producer, for the film's problems. Eisenstein hoped to pressure the Sinclairs to insinuate themselves between him and Stalin, so Eisenstein could finish the film in his own way. Unable to raise further funds, and under pressure from both the Soviet government and the majority of the Trust, Sinclair shut down production and ordered Kimbrough to return to the United States with the remaining film footage and the three Soviets to see what they could do with the film already shot; estimates of the extent of this range from 170,000
