Blood Legacy was also released as Legacy of Blood (as was a like-titled, though dissimilar, 1978 film). Looking older than dirt, John Carradine plays a crotchety millionaire who wills his fortune to his estranged children. There is, of course, a proviso. The kids, all grown up and none too savory, must spend a week in Carradine's estate. Naturally, this leads to a lot of petty spitefulness...which in turn leads to murder. Jeff Morrow and Faith Domergue, who in happier times co-starred in This Island Earth, show up as two of the heirs, as do 1950s favorites Merry Anders and Dick Davalos (James Dean's brother in East of Eden). Rudolfo Acosta is top-billed as a local sheriff who must contend with seven days' worth of carnage.
