The cast and crew of the “Fifty Shades Of Grey” sequel were filming on location in the south of France when a man drove a truck into a crowd of Bastille Day revellers in a terrorist attack in July. Stars Jamie Dornan and Dakota Johnson and the crew were shaken but unharmed in the attacks that killed 85 people in Nice. Following the attack, it was business as usual on the set of “Fifty Shades Darker”.

“It’s a strange feeling. You feel sort of bereft, but you feel an odd sense of relief that your family are fine and it seems really frivolous the following day to be making something as silly as a movie,” Dornan tells ET Canada.  “You’re contractually obligated to work the next day and you just have to get on with it but it was a very odd day to work, I have to say.”

The 34-year-old Irish actor has since wrapped production on the sequel, and is switching gears with his next project, “Anthropoid”.

Together with fellow Irishman Cillian Murphy, Dornan stars in the extraordinary true story of Operation Anthropoid, the WWII mission to assassinate Hitler’s third-in-command.  The duo play two of the Czech soldiers tasked with carrying out the assassination order against SS General Reinhard Haydrich, the man responsible for the Final Solution.

ET Canada caught up with the actors to get the latest on “Anthropoid” and Murphy’s next role in Christopher Nolan’s “Dunkirk,” which also stars One Direction’s Harry Styles.
