Temple will be joining fellow castmate Daniel Radcliffe, and possibly Joe Anderson, Kelli Garner, and Max Minghella, who are apparently in talks for roles.
The film is the story of a young man whose girlfriend is brutally raped and murdered, and he becomes the prime suspect. After a night of hard drinking, he awakens the next morning to find horns growning from his forehead, which have the power to make people not only confess their sins, but to force them to give in to their darkest impulses.
Alexandre Aja's past works have included the reworking of "The Hills Have Eyes" and "Haute tension"(English title: High Tension).
Radcliffe's last production was "The Woman in Black", and he is currently involved in "Kill Your Darlings" and "The F Word".
Juno Temple can be seen in "The Dark Knight Rises" and "Jack and Diane", while she has recently finished work on "Lovelace".
