There is a DVD advertised on a few of the online music stores for example here. On all sites however they give no info apart from the release date of 23rd August. Aparently this is what it is though..

INSIDE DAVID BOWIE AND THE SPIDERS 1969-1972
Featuring rare TV footage and exclusive interviews with
surviving Spiders Trevor Bolder and Woody Woodmansey,
this superb film includes a masterclass with Bolder explaining
how the bass lines for these amazing songs were created in
the studio.


Might be better than Origins of a Starman at least?

I agree with the above statement.
