From Beyond (1986)

On the headless heels of the brain-splattering horror classic Re-Animator (1985), writer-director Stuart Gordon turns again to the way-out works of author H.P. Lovecraft for From Beyond (1986). Also returning are stars Jeffrey Combs, as our scientist hero, and Barbara Crampton, this time in the guise of a psychiatrist. Mucking things up quite literally is Dr. Pretorius (Ted Sorel), whose theories regarding the human brain's pineal gland as a gateway to invisible dimensions that constantly surround us prove all too fluidly, grotesquely true. Speaking of fluids, Ted's tush is appropriately soaked when he goes bare 33 minutes in, and Dawn of the Dead's Ken Foree may cause leakage brandishing a boner in his briefs at the 44-minute mark.
