Kate Jackson and Robert Wagner in Death at Love House.

For a few fun years in the 1970s, Kate Jackson was the queen of the humdinger ending. From Killer Bees to Death Cruise and Satan’s School for Girls, she delivered morbid laughs with a winsome smile. Unlike those offerings, director E.W. Swackhamer’s Death at Love House (1976) isn’t particularly humorous—at least not intentionally—but its overwrought ending might remind you of the flaming baby scene from Susan Slade, which puts it in a league of its own.

Jackson’s Donna Gregory is the newly pregnant wife and writing partner of Joel Gregory, Jr. (Robert Wagner). Together they’re probing the history of Joel Sr., the father Junior barely knew, and his turbulent Hollywood romance with the late Lorna Love (Marianna Hill), a legendary bombshell actress. If the actors aren’t entirely convincing as Didion and Dunne knockoffs, modern audiences would have to uncomfortably concede that Wagner (who also plays Joel Sr.) is right at home in a story about the sordid circumstances surrounding the premature death of a beloved actress.
