This remarkable black comedy is often listed as a horror film, yet it has more nervous laughs than shivers. It’s a solid idea: cruelly maginalized old folks get madder than hell and just won’t take it any more. Or maybe they simply go nuts. The cast of ‘over seventies’ playing over eighty is just marvelous, and one murderous little pixie is a delight: Paula Trueman. Things do become absurd, but the universally-understood premise stays firm: we’ll all be there sooner or later. “A Murder A Day Keeps the Landlord Away.” With Peter Brocco, Frances Fuller, William Hansen, Ruth McDevitt, Paula Trueman, Ian Wolfe, Linda Marsh, Douglas Fowley, Kenneth Tobey. On Blu-ray from KL Studio Classics.
