The newest Stephen King movie, The Dark Tower, opened in US and Canadian theatres this weekend, but it wasn’t the hit that Sony might have wanted. It made $19.5 million over the Friday-Sunday period, good enough for No. 1. Rounding out the top five movies at the US box office this weekend were Dunkirk ($17.6 million), The Emoji Movie ($12.4 million), Girls Trip ($11.4 million), and Kidnap ($10.2 million).
