Twenty years ago, David Arquette took a gamble that may have ruined his career: In an ill-fated attempt to promote “Ready to Rumble,” Arquette became a part of World Championship Wrestling’s ongoing storylines and eventually emerged as its world championship. Diehard fans were pissed.Needless to say, the blowback sent Arquette on a downward spiral of addiction and depression from which he never fully recovered. David Darg and Price James’ documentary follows Arquette as he anticipates a questionable return to the ring. An unnerving black comic exploration of celebrity, addiction, and personal responsibility, this wily portrait of Arquette’s unorthodox comeback suggests the surprising love child of “Sunset Boulevard” and “The Wrestler.” -Indie Wire
