Just how bad is this spineless $60 million space wreck? So bad is Supernova that the guy who directed ''Brewster's Millions'' -- Walter Hill -- took his name off. Spader tries out his newly buff bod and gravelly hero voice as the captain of a medical vessel that rescues a sinister scavenger (Peter Facinelli) with a rage on for the good doctor Bassett. The upshot of this unreleased R rated cut is that now Robin Tunney's breasts get more screen time than Robert Forster.
