By the late 1940s, Disney's involvement during production had shrunken noticeably. As he was occupied with trains and the filming of "Treasure Island", the directors were left to exercise their own judgment more on details. Although Disney no longer held daily story meetings, the three directors still communicated with him by mailing him memoranda, scripts, Photostats of storyboards, and acetates of soundtrack recordings while he was in England for two and a half months during the summer of 1949. When Disney did not respond, work resumed and then had to be undone when he did. In one instance when Disney returned to the studio on August 29, he reviewed Luske's animation sequences and ordered numerous minor changes, as well as a significant reworking of the film's climax. Production was finished by October 13, 1949.
