EXCLUSIVE: Neil Marshall is in early talks to direct Hellfest, the CBS Films horror project about a costumed killer who systematically slaughters the unsuspecting visitors who come to a theme park on Halloween night. The plan is for this to be his next movie and start production by summer next year. The hope is to launch a horror franchise. Scripted by William Penick and Chris Sey, Hellfest is produced by Gale Anne Hurd through her Valhalla Entertainment banner. Marshall last helmed Centurion, and before that Doomsday and The Descent. He’s currently in post production on Blackwater, an episode in the second season of HBO’s Game of Thrones. He’s repped by Principato-Young, ICM and Carlos Goodman.
