Bastille Day (M) James Watkins’s Paris-based crime thriller Bastille Day deals with contemporary terrors, ones that are heavy in mind. The ignition here is a bomb inside a teddy bear. It goes off at Place Pigalle, killing four people. The bombing scene is particularly effective, not least because it is so ordinary. What follows is a drama lifted by an entertaining script, oldfashioned action scenes and a few surprising twists. Big Idris Elba (as CIA agent Sean Briar) chasing his not-as-big co-star Richard Madden ( Game of Thrones) over slanted Parisian rooftops is wonderful to watch. This is a slick, clever film, and while viewers will work out who the real baddie is before the end, Elba and Madden invest their characters with interesting unanswered questions.
