In 2006, Suvari voiced the character of Aerith Gainsborough for the Square Enix–Disney video game "Kingdom Hearts II" and the English-language version of Square Enix's film "Final Fantasy VII Advent Children", which was released straight-to-DVD in North America and became one of the best-selling animated movies in the country. Opposite Katherine Heigl, Suvari starred in the independent comedy "Caffeine" (2006), playing the staff of a London coffeehouse, and in the biographical drama "Factory Girl" (2006), she played a friend and roommate of 1960s underground film star and socialite Edie Sedgwick (played by Sienna Miller). While "Caffeine" went unnoticed, "Factory Girl" received a limited theatrical release amid a negative critical response. In the crime drama "Brooklyn Rules" (2007), directed by Michael Corrente and co-starring Freddie Prinze Jr., Alec Baldwin and Scott Caan, Suvari portrayed a society girl and the girlfriend of a man involved with the Brooklyn mafia in the 1980s. The film was released for selected theaters and received mixed reviews, but "Variety" remarked that Suvari, "who might have played [her part] as a cliché, gives a real performance". Her next film was the psychological thriller "Stuck", where she took on the role of a woman who commits a hit-and-run and leaves the victim clinging to his life in the windshield of her car. Inspired by a true story, the film premiered at the Cannes Film Market, and while "Stuck" found a limited theatrical release, it was favorably received by critics and audiences. "Austin Chronicle" found the film to be "buoyed by queasy, easy performances" from Suvari and Rea, who were considered "well-matched in uneasy roles" by "Empire". By the late 2000s, Suvari continued to act in smaller-scale projects, obtaining four back-to-back roles in films released throughout 2008, including one made-for-television film. "Day of the Dead", a remake of George A. Romero's horror film of the same name, saw her portray what was described as a "butch military leader capable of fending off a zombie holocaust", by "DVD Talk". The film received a straight-to-DVD release and was panned by critics. In "The Mysteries of Pittsburgh", a film adaptation of writer Michael Chabon's novel, Suvari played a strange girl who works at a book shop and becomes romantically involved with the well-mannered, intelligent son of a Jewish gangster.
