I just found out that TANGO & CASH and NOWHERE TO RUN writer Randy Feldman penned the script.
Announced in late 1987, this was to follow Craig Baxley's collaboration with producers Joel Silver and Lorimar's Bernie Brillstein (GHOSTBUSTERS) after ACTION JACKSON and was way before they got to do DARK ANGEL / I COME IN PEACE (yet for a while I thought they were the same project which is not the case).
Dolph was to play an alien hitchhiking in the Nevada desert, got picked up by a repo man and they ended up in Las Vegas. Filming was about to start (spring 1988 - after RED SCORPION?) when it got shut down a few days before because Silver and Brillstein argued over who the co-star would be (plus the Writers Guild going on then also have had something to go with it).
EDIT:
Randy Feldman is the son of THE WILD BUNCH producer Phil Feldman and the brother of GOLDEN CHILD & SPECIES writer Dennis Feldman.
