Due to scheduling conflicts, Morgan Freeman and Gerard Butler don't appear in the same scene together in person. The scene in the hallway at the White House uses body doubles, and doesn't show faces.
Olympus Has Fallen (2013) director Antoine Fuqua refused to direct this sequel because he didn't like the script.
The jogging sequence at the start of the film, was filmed in Kensington Gardens in central London.
Oddly, even though Angela Bassett only accepted her role in the previous instalment to work with Morgan Freeman. In this instalment, she did not work with him at all, their characters share no scenes and never interact.
Morgan Freeman added his voice to the directions mobile app 'Waze' to support the release of this movie.
