On November 24, Eisenstein signed a contract with the Trust. The deal was "upon the basis of Eisenstein's desire to be free to direct the making of a picture according to his own ideas of what a Mexican picture should be, and in full faith in Eisenstein's artistic integrity." The contract also said that the movie would be "non-political." The money first came from Mrs. Sinclair and would be "not less than Twenty-Five Thousand Dollars." The schedule for making the movie would be "a period of from three to four months,". The contract also said that "Eisenstein...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..." An addition to the contract, dated December 1, allowed that the "Soviet Government may have the [finished] movie free for showing inside the U.S.S.R." Reportedly, it was verbally decided that the movie was expected to be an hour long.
