Touching Soap Films is part of Springer VideoMATH, a series of mathematical videos. The series, edited by T. Apostol, J.P. Bourguignon, M. Emmer, H.C. Hege, K. Polthier, is described as consisting of "videos covering topics from mathematics and its related fields, such as computational science, scientific visualization and mathematical physics. The level ranges from research to teaching, and some of the videos address not only the experts but all who have an interest in science."
This video is a computergenerated adventure into the world of minimal surfaces. Historically, the beginning of this field of study dates back to at least 1760 when Lagrange posed the question, "Does there exist, for each arbitrarily complicated boundary curve, a surface of least area (i.e., a minimal surface)?" The purpose of this 40minute featurette is to expose its audience to both the historical development and modern research in the field. It does certainly leave an impact on the viewer, but this may not be entirely due to the exposition of mathematics.
Let me describe the setting of this video. The underlying story is an adventure through a museum (of sorts) of surfaces. A boy by the name of Kalle is intrigued by the plethora of surfaces he encounters along his journey to this building and decides to investigate further. He proceeds inside the building and after a rather bothersome runin with a computer sentinel standing guard of the building (as though it were a military fort of some kind), he stumbles into the shrine of the granddaddy of all surfaces. Needless to say his curiosity gets the best of him and he manages to demolish it with one foul swoop. He is immediately escorted to the professor's office where his lesson on the history of minimal surfaces begins (of course, after being chastised for his utter carelessness). The professor goes on to explain how problems concerned with minimal surfaces can be studied with the help of soap films. The discussion lasts for about 25 minutes until he is catapulted out of the building by some strange amusement ride.
Yes, this is a mathematics video, really. The discussion of mathematics, although sometimes superficial and at other times too brief, is generally palatable. The computergenerated animation sequences involving these surfaces were truly amazing and certainly aided in the conceptualization of some complex mathematics. The video was claimed to be amenable to a general audience interested in science, but would also perhaps have educative value for more advanced students of mathematics (all the way up to graduate students of differential geometry). This claim seemed a bit absurd, seeing as it is difficult enough to teach a class in which the students' backgrounds do not differ by such a vast gap. So, to test whether this assertion might have some degree of validity, I showed it to my undergraduate differential equations class. Most of them found the area of study interesting, but the following negative comments were recurring:

The computer voice was annoying and hard to understand, and the music was too overpowering.

It was difficult to distinguish the information from the entertainment. I think some of the informative aspects of the video were overwhelmed by the "too cute" story line. Also, the length of the video could be decreased by 5 minutes if only the boy tiptoed faster.
I must say that I concur with these remarks. I have some background in elementary differential geometry and I still found it difficult to comprehend what the main points were, at times. It seems that the technology, although it works wonders, can be overwhelming and rather than having aided in one's understanding, it has hindered it.
The video does have some redeeming qualities and you can certainly tell that a vast amount of effort went into its production. However, in my opinion, it might be better suited for a high school (or even middle school) audience as a "motivational" device used to stimulate interest in mathematics. The creators provide a rather detailed booklet to accompany the video, as well as a link to a web site containing material related to the video (applets, animations, and the like).
