HAL & HARPER

HAL & HARPER

From Cooper Raiff (Cha Cha Real Smooth) comes Hal & Harper, a wry and heartfelt 8-episode series about two siblings whose closeness is both their comfort and their curse. Hal (Raiff) and Harper (Lili Reinhart) have built their adult lives side by side in Los Angeles, tethered by a lifetime of inside jokes and shared pain. 

When their father (Mark Ruffalo) announces he’s having a baby with his girlfriend, Kate (Betty Gilpin), it forces the siblings to reexamine their past and reckon with the versions of themselves they’ve carried into adulthood. As the lines blur between closeness and codependence, memory and reality, Hal & Harper explores how a bond formed in childhood can shape every relationship that comes after—for better or worse.

Also starring Betty Gilpin (GLOW), Havana Rose Liu (Bottoms), and Alyah Chanelle Scott (The Sex Lives of College Girls), the series captures Raiff’s signature blend of humor, melancholy, and emotional clarity, offering a tender and incisive look at family, identity, and the long shadow of a complicated upbringing.
