The Return Of The Living Dead. 1985.
Two employees at a medical supply warehouse open a container release a gas which helps re-animate the dead.
A salute to Clu Gulager (R.I.P another good actor gone) he stars as Burt who owns and runs a medical supply building hiring James Karen and Thom Matthews who release the gas and then all breaks loose in the nearby cemetery where a group of teens are having a party. George Romero gave us some serious zombie horror that is mentioned in this, Dan O'Bannon added in some comedy and Linnea Quigley dancing about naked.
