Dead Heat

There's Riggs and Murtaugh, Tango and Cash, even Turner and Hooch, but now you can add Bigelow and Mortis to the long list of cop movie buddies - only this time in the action/comedy/horror genre. In Dead Heat, Detectives Roger Mortis (Treat Williams) and Doug Begelow (Joe Piscopo) get called to the scene of a jewelry store robbery in progress, where they find a couple of thugs that can take a lickin' and keep on tickin'.  These guys are soaking up bullets but they don't seem to be adversely effected by being pumped full of lead.  After Mortis gets the bright idea to just take them down with a cop car, they find some startling information about these crooks once the coroner get's a chance to examine them.  They've been to the morgue before, and not just for a sight seeing tour - they were admitted as stiffs just a short time earlier and were given the full service treatment, autopsy and all.  So, if these guys are dead... how were they able to attempt a jewelry store robbery?
