Lyne's chilling film bombed in the States, probably because of its origins in the murkier side of the now done-to-death Vietnam War. But, messy and maddening though some of it is, Jacob's Ladder is also a truly scary film which is never simply a war or horror vehicle. Jacob Singer (Robbins) is a man whose life totters continually between past, present and future, between reality and terrifying illusion brought on by his experiences in Vietnam, where his unit was dosed with a vicious derivative of LSD to improve its killing power. Where the problem arises is that this scenario is only one alternative in the life of a man variously shown as divorced, studying and co-habiting, married and prosperous with children, or dead on a Vietnam field-hospital table. But Lyne's giddying, unsettling direction conjures up moments of horrifying hallucinogenic power from the bad-trip hell of his protagonist.
