In screenwriter Michael Kennedy’s newest project, It’s a Wonderful Knife, a teen girl who wishes she had never been born sees visions of an alternate reality in which the serial killer she stopped is allowed to run rampant through the town. It’s a Wonderful Knife takes obvious inspiration from the high-concept classic It’s a Wonderful Life, Just as Happy Death Day does with Groundhog Day and Freaky does with Freaky Friday. The planned Happy Death Day and Freaky crossover may no longer be happening, but with It’s a Wonderful Knife, Kennedy is delivering a worthy successor and capping off an unofficial trilogy of high-concept slasher retellings.
