I've just watched this. A rather good take on Frank Baum's story I thought.
I just remembered, Richard Dreyfus(the Wizard) was also in the 80's comedy Tin Men with Danny DiVito playing dodgy salesmen. Anyone seen that one?
Haven't seen the Danny DeVito aluminum siding salesman film, but have seen the one with Zooey Deschanel as DG (Dorothy Gale) a couple times. I consider it a satirical comedy with a bit of resemblance to OZ: a funny film for grown-ups only.
