There is a new Belushi Doc on Showtime that debuted last week, its fantastic. A lot of unreleased material.
We had a Blues Brothers doco on TV here in Australia years ago which showed a lot of un-released footage, I especially remember the footage of were they parked their car every night, it was in a sort of tunnel under I think a bridge or overpass. it explains were the car got its power from as the car was zapped by some force while in the tunnel, it explains a lot. Also I think he was the Mayor or some official of Chicago at the time who did not approve of the car chases in the streets, he was I think overruled, his name is mentioned a couple times in the movie.
