Help: Trying to find a movie title...

Tools    





...the movie Im looking for is not a classic by any means, but a decent flick I saw once in the 90's...any help would be greatly appreciated...


PLOT

a gang of professional thieves search for long lost hidden treasure in the projects of a large city, more specifically a vacant apartment building...they force an "expert" on the treasure into helping them find it...they run into curious local thugs during their hunt

anybody know it???

This sounds familiar, but the film I'm thinking of has two firemen find a map to some valuable goods in the ceiling of a derelict building apartment, a group of thugs turn up because their on their "turf" and violence escalates.

Did you know that in the 1980s movie PREDATOR the titular character was not originally portrayed by Kevin Peter Hall. It was in fact Jean-Claude Van Damme donning a much more insect inspired full body suit before he left the production which then led to the recasting and redesigning of the famous hunter.
