“Sextuplets,” the latest made-for-Netflix comedy from the “White Chicks” alum Marlon Wayans (following the 2017 rom-com “Naked”), is about as funny as an amputation and nearly as painful. Wayans stars as Alan, who seeks out his birth mother on the eve of his first child’s birth and discovers he was one of six sextuplets — all of them played by Wayans.

Hilarity, in theory, ensues, although if there is a solid laugh to be found in “Sextuplets,” this viewer missed it. The writers pack their script with maddeningly familiar elements: a pending partnership at Alan’s company, a zany odd-couple road trip and (two for the price of one) a car chase en route to a hospital delivery room. But each comic set piece decomposes on the screen , lifeless and hopeless .

The supporting players do their best — Bresha Webb , as Alan’s put-upon wife, is spirited and engaging, and Molly Shannon is funny, as Molly Shannon always is — but this is Wayans’s vehicle, and in that respect, it’s an embarrassment. The picture’s most direct inspiration is “The Family Jewels,” in which Jerry Lewis plays six brothers, though the makers of “Sextuplets” are clearly attempting to replicate the magic of Eddie Murphy’s remake of Lewis’s “The Nutty Professor” (and its sequel).
