Twilight star Ashley Greene has joined the edgy indie thriller Summer, about a family of serial killers. Horror filmmaker Lee De Marbre is directing the project.

According to The Hollywood Reporter, Stephen McHattie, Barbara Niven and Peter Mooney play the deranged kinfolk that Greene's character encounters on her quest to find the father she's never known.

The film is halfway through its Ottawa shoot, and footage will be shown in the fall at AFM.
