Servant season 4 is underway, with the Apple TV+ thriller poised to deliver an exciting conclusion to the story that began in 2019. Created by M. Night Shyamalan, Servant centers around a Philadelphia couple stuck in mourning after the unthinkable loss of their child. In signature Shyamalan fashion, all is not as it seems, and each season of the show has elevated it to new heights in terms of both drama and suspense. Servant stars Lauren Ambrose as Dorothy Turner, Toby Kebbell as Sean Turner, Nell Tiger Free as Leanne Grayson, and Rupert Grint as Julian Pearce. The collaboration between Shyamalan and Grint on Servant clearly was a fruitful one, as the actor became one of the central cast members of Shyamalan's well-reviewed Knock at the Cabin.
