Warlock is an occult schlock-o-rama, with special effects so low-budget they might have come out of a joke shop. There are gelatinous eyeballs, a rubbery severed tongue, and a psychic (Mary Woronov) who's transformed into a demon with big yellow teeth. (Trust me, it's veddy scaddy!) Mostly, though, there are two respectable British actors Julian Sands and Richard E. Grant standing around graveyards and farmhouses spouting pseudo-literate gothic gibberish. As the Satan-fighting good guy who arrives from 17th-century Boston, Grant gets to display little of the sputtering, high-octane dementia that made him such a perverse delight in Withnail & I. The movie would have been more entertaining if he had played the warlock.
