Prince of Darkness (1987)

Prince of Darkness (1987): written and directed by John Carpenter (writer's credit to 'Martin Quatermass'); starring Donald Pleasence (Priest), Jameson Parker (Brian Marsh), Victor Wong (Professor Birack), Lisa Blount (Catherine Danforth), and Dennis Dun (Walter): 

John Carpenter's ode to cosmic horror also nods to Nigel Kneale's quintessential 1950's BBC Quatermass serials that became movies in the 1950's and 1960's, most specifically Quatermass and the Pit, aka Five Million Years to Earth. It's not just the subject matter of Prince of Darkness that cues us to the Quatermass connection. Carpenter adopts the pseudonym 'Martin Quatermass' for the screenplay.

The quantum physics is completely ludicrous if you've done any reading in the subject at all. Especially as we're shown what is supposed to be a graduate class in theoretical physics. But Carpenter is pitching his cosmic horror to a general audience, so we'll give him a pass. I'm not sure I can give him a pass on Jameson Parker's mustache, though, or his character's early, stalkery behaviour. Oh well. We don't always get Kurt Russell as the protagonist of a John Carpenter film. But we should!

Basically, there's a jar of liquid Satan in the basement of an old church in Los Angeles. The last keeper-priest of the church has died. Even the Roman Catholic Church hierarchy has forgotten about the church, the secret order named The Brotherhood of Sleep, and, you know, JAR OF SATAN. 

JAR OF SATAN

The great Donald Pleasence, named only 'Priest' in the credits, travels to meet with quantum physicist Victor Wong. The RCC wants scientific proof that the Jar of Satan is actually a Jar of Satan before they proceed with trying to avert the rapidly approaching apocalypse.

Why is the apocalypse coming? Well, the Satan Jar seems to be awake and trying to either escape the jar or reincarnate itself somehow.

Shenanigans ensue over the course of one bad weekend with the Jar of Satan. Certain things are underwhelming, but the underlying pseudo-scientific explanation for evil -- that it was an invading force for another universe -- is suitably cosmic and disturbing. 

Kudos also to Carpenter for being here and in other films far ahead of the Hollywood curve in hiring Asian-Americans in non-traditional roles. It's an underlooked trait of his oeuvre. Also, Victor Wong is always hilarious, even when he's explaining Quantum Physics for Dummies. Highly recommended.
