The Boys season 2 breakout star Antony Starr (heh) and Master of Sex actress Lizzy Caplan have both signed on to star in Cobweb, a Lionsgate thriller which will begin production later this month.

Cobweb will be directed by Samuel Bodin, based on a screenplay by Chris Thomas Devlin. It centers on a small town, in an ordinary house that seems like any other, where a young boy hears a mysterious tapping from inside the walls – and suspects his parents are hiding a terrible secret.

Caplan will play Carol, the mother of the young boy, while Starr is Mark, the boy’s father. Woody Norman, whose credits include Poldark and the forthcoming C’mon C’mon, stars as Peter, a timid boy who becomes increasingly troubled by the strange tapping he hears within the walls at night. Cleopatra Coleman, known for In the Shadow of the Moon and The Argument, will portray Miss Devine, Peter’s substitute teacher who is filling in at the local elementary school.

Cobweb will be produced by Roy Lee through his Vertigo Entertainment banner along with the Point Grey team of Seth Rogen, Evan Goldberg, and James Weaver, as well as Jon Berg.
