I think I stumbled across this, on one of the cable movie channels back in the dark ages (aka the 90's). It looks really familiar .Shakma (1990)

You boys haven't lived until you watch the substandard cess·pool of a B film, Shakma.
Shakma (also known as Panic in the Tower) is a 1990 American horror film directed by Tom Logan and Hugh Parks. It stars Christopher Atkins, Amanda Wyss (A Nightmare on Elm Street ), Ari Meyers and Roddy McDowall.
Shakma has a lot going for it. A rabid baboon killing a team of medical school jackasses is inherently entertaining. Six medical students and a professor are locked inside a medical building with a murderous experimental baboon when an innocent game of Dungeons and Dragons turns deadly.
Yup, the acting was so painful . You know it is a sad day as an actor when you are shown up by the likes of Sam - Christopher Atkins! Our hero. Atkins acting compared the the rest of the cast was "Oscar worthy". Truth be told Christopher Atkins was more than decent in he's role. The stand-out is baboon TYPHOON as SHAKMA . He does nothing but chase the students into various rooms throughout the building, whereupon he screeches and throws himself repeatedly against the door until he gets bored. I cannot even begin to describe how much doors piss Shakma off. He absolutely hates the things and it is totally gut busting hysterical to watch.... As absurd as this film was I enjoyed watching "Shakma" rip, mangle and maul the entire eminently forgettable cast. I can see how this film has gained a small cult following over the years.
Shoo , Skakma , shoo ! Leave sexy Tina..... "A Nightmare on Elm Street" alone.
