The new trailer for “The Girl on the Train” doesn’t explain how anyone could let Justin Theroux go, so we’ll have to wait for the movie to hear Emily Blunt’s explanation for that romantic oversight. (Unless you’ve read Paula Hawkins’ popular novel, on which it’s based.) One could assume it’s because she has stalker tendencies. Blunt plays Rachel Watson, a divorcee who forms an obsession with a mysterious young couple living down the street from her ex-husband.
Opening Oct. 7, “The Girl on the Train” is destined to be one of fall’s big hits. The novel was heralded as “the next ‘Gone Girl,’” and the movie is directed by crowdpleaser Tate Taylor (”The Help,” “Get On Up”). It also stars Rebecca Ferguson, Allison Janney, Luke Evans, Haley Bennett and Lisa Kudrow.
