I'm searching for Hannes Alfvén's Nobel Prize lecture for his Nobel Price in Physics in 1970. The full text of his price acceptance speech can be found online as PDF below, but I'm wondering if a film or video recording is also available.
Nobel Lecture, December 11, 1970
Plasma Physics, Space Research and the Origin of the Solar System

The cosmical plasma physics of today is [...] to some extent the playground of theoreticians who have never seen a plasma in a laboratory.
Many of them still believe in formulae which we know from laboratory experiments to be wrong.
[...]
It turns out that in several important cases this approach has not given even a first approximation to truth but led into dead-end streets from which we now have to turn back.
[...]
It is now obvious that we have to start a second approach from widely different starting points. The two different approaches can be summarized in Table 1.

First approach

Magnetic field lines are frozen in and move with the plasma.
Electromagnetic conditions illustrated by magnetic field line picture.

Second approach

It is equally important to draw the current lines and discuss the electric circuit.
Electrostatic double layers are of decisive importance in low density plasmas.
