Hi Trevor. 
Great attempt, which will get much support I hope. 
Some remarks:
If I'm not mistaken a film is considered as a "short" up to 40 (or 50?) minutes. 60+ is already a feature.

I remember that we have the australian short Harvie Krumpet covered, as well as my review of the 5 minute film Feet of Song from the UK. Also wpqx has listed some of the films by Les Blank, shorts by Kubrick, there is also my review of Les Mistons, and some others i don't recall at the moment.
Hope this helps a bit.
