A comedy that’s more screw-loose than screwball, Edward Hall’s “Blithe Spirit,” a ludicrous adaptation of Noël Coward’s 1941 stage play, reimagines its source material as little more than a slip-and-fall farce.

Dan Stevens stars as Charles, a near-parody of a blocked writer who’s introduced literally eating the words he has just typed. Commissioned to write a screenplay of one of his best-selling novels, Charles is desperate: Bedeviled by bedroom dysfunction (“Big Ben’s stopped chiming,” he whines to a friend), he hopes to find inspiration by inviting a disgraced psychic (Judi Dench) to host a séance in his imposing Art Deco mansion.

What gets released, though, is not what Charles expects as the ghost of his first wife, Elvira (Leslie Mann), killed in a riding accident years earlier, moves in and takes umbrage at her replacement (Isla Fisher). Elvira, visible only to Charles and the audience, and blessed with a well-stocked ghostly wardrobe, is anything but blithe: Wrecking the garden and throwing knives at the help, she proves as hard to get rid of — and about as entertaining — as black mold.

Propelled by tiresome characters and tortured setups, “Blithe Spirit” (originally filmed by David Lean in 1945) is a dated curiosity. Merging upper-crust twittery with hocus-pocus nonsense not even Dench can sell, the dialogue encourages Elvira to nag and everyone to over-emote. Surplus buffoonery and a new ending add nothing to the original, leaving us with a movie that obsesses over death while showing all too few signs of life.
