See How They Run director Tom George has reassured Agatha Christie fans that he and the team around the movie have been very careful to avoid spoiling Christie's play .
West End audiences have been told to keep the ending of the murder-mystery play to themselves ever since it was first staged way back in 1952 — making it the longest-running continuous production in history. George's film, penned by British comedy veteran Mark Chappell, follows police officers played by Sam Rockwell and Saoirse Ronan as they investigate a death at the theatre where the play is being performed.
See How They Run is in UK cinemas from 9 September.
