The casting process of Columbia and Imagine’s untitled Gus Van Sant drama is keeping with the project’s familial theme.

The feature, on which Bryce Dallas Howard is teaming with father Ron Howard to produce with Brian Grazer, is opening its arms to Dennis Hopper’s son Henry Hopper, who will star opposite Mia Wasikowska.

Schuyler Fisk, daughter of Sissy Spacek, also is boarding the movie.

The drama revolves around a teenage boy and girl who share a preoccupation with mortality.
