Here's some pictures for the already-existing Darkman gallery, which has none.
A kind of maroon-ish car. Chrysler, maybe? 1 star, just a background car.
Another maroon-ish car, used in the opening action sequence. 2 stars.
Green four-door car, also used in the opening action sequence. 2 stars.
Lincoln Towncar, one of two used by Durant's gang throughout the movie. 4 stars.
Strack's Lincoln Towncar stretched limo. 2 stars.
Oldsmobile Cutless Supreme, Sam Raimi's favorite car, seen in the chase scene towards the end. 1 star.
Truck Darkman attaches Durant's helicopter to. 3 stars.
Truck that runs over one of Durant's gang members; I think it's the same kind of truck as the one above. 2 stars.
Taxi. 2 stars.
Some kind of station wagon that Pauly, one of Durant's gang, falls onto. 1 star.
Black limo at the cemetary. 1 star.
And that about does it for Darkman, I think.
