Director Ron Howard ("Beautiful mind", "Iron fist Man" and "Fast Sex") will direct the thriller "the ex Girl" based on the author J.P. Delaney's novel of the same name. The novel version of the ex-Girl will be published next fall, but Universal Studios bought its film adaptation rights early. In the novel, a woman with psychological trauma is fascinated by a minimalist house and falls in love with the designer of the house. But she later found out that another woman had died in the house three years ago.
