La Villette's Cinema en Plein Air

If you don't mind heading to the 19th you can try something that is a long running summer event, La Villette's outdoor cinema. You can start queuing at 7, but the films start at sundown and are free. This year's theme is "dance" and of course features a fair number of English films (Pulp Fiction, Black Swan, West Side Story). All films are in version orginal so expect English with French subtitles. It runs from July 20 to August 21st. The list of movies is here. Be sure to bookmark their Facebook and Twitter as they will report cancellations there.
