Grumman footage of LEM construction

In the 1998 HBO series, "From the Earth to the Moon", the following is
depicted in the segment entitled 'Spider', about the design and construction
of the LEM. A Grumman employee whose name escapes me tells another to
document EVERYTHING on film (16mm I think).

Does anyone know if Grumman really did this and if so has any of this
material been collected and made available to the public? I did some
Googling and can't locate anything like this.
