These film clips are collected from YouTube. The links here appear to be stable. Nonetheless, sometime things change. If you do not find a specific film, try doing a YouTube search. Several other short selections of Jung speaking appear from time to time on YouTube, but all of those are extracted from these major film sources.
C. G. Jung: Face to Face — The John Freeman Interview (1959)
Recorded for the BBC "Face to Face" TV series in 1959, this is the entire 40 minute interview with Dr. Jung, completed just 2 years before his death. The copy linked here is a high-quality restoration of the original film. (As with many YouTube videos, this is originally copyrighted material, and occasionally a copy is removed. If you search YouTube, you will usually find another copy.)
The Richard Evans Interviews (1957)
Filmed in 1957 by Dr. Richard I. Evans for the Department of Psychology, University of Houston. Dr. Evans conducted four one-hour interviews with Jung at the Eidgenossische Technische Hochschule (ETH, Federal Institute of Technology) in Zurich, on August 5-8, 1957. The conversations were filmed as part of an educational project designed for students of the psychology department. Evans is a poor interviewer, but Jung compensates well. This is a very important documentary record.
This edition of the interviews was released on DVD by Pennsylvania State University in 2007. This is a good transfer of the original (but occasionally scratched and aging) film. Also note that the flow of the four interviews has been edited; Evans interweaves clips on various subjects from different individual sessions. I believe this is how Evans edited the original copy of the interviews for his project.
Matter of Heart — The Classic Documentary on Jung (1985)
This is the classic 1985 film about C. G. Jung, written by Suzanne Wagner and produced by Mark Whitney. You must watch this film, it was produced with great care and insight. This is a good copy of the DVD version of the film. This film appears from time to time on YouTube, but it is copyrighted and is often removed, only to be reposted again later. If you wish to view it, considering buying or renting a copy. You can view it free with Amazon.com Prime, or purchase it for download and viewing.
Archival film showing Jung working on his "Aion Lapis" at the Tower (1951)
This film footage was shot between about 1950 and 1951 by Jerome Hill. It shows Jung beginning and finishing work on his famous stone at the Tower in Bollingen, along with short scenes from his daily life. The film shot by Hill was finally edited together in 1991 in a rather primative way. That version appears here.
People sometimes ask, "Who is the younger woman frequently seen in the film with Jung (usually smoking a fat cigarette)?" This is Marie-Jeanne Schmid. Schmid was the daughter of Jung's friend Hans Schmid, who had died in 1932. She worked as Jung's secretary for twenty years, and was a very close friend to the family. Thus in this film you see her at Jung's side, shuffling letters and papers, getting books, and eating lunch with Dr. and Mrs. Jung. (Around 1952 Marie-Jeanne married and retired from working for Jung. This was quite a disaster for Jung. Eventually he found the help of Aniela Jaffe, who served as Jung's secretary up until his death in 1961. In 1957 Jaffe conducted the interviews with Jung which she edited into his memoir Memories, Dreams, Reflections.)
Jung, Gnosis and Religion - BBC Documentary (1984)
Part of a 1984 BBC Series, titled "Sea of Faith," this 16 minute clip offers a fine introduction to Jung's understanding of religion, myth, and the tradition of Gnosis. It is the best brief film introduction to Jung that I have encountered.
