Like with Olympus Has Fallen (2013) and London Has Fallen (2016), Morgan Freeman has openly admitted in interviews that he did this movie mainly for the money. As he explained for the previous two: "Money. It's the third in a series it pays better than the first one. I get to play the president again, I'm in a successful series, I'm working with a guy I really admire and like. It's perfect." When asked whether he still felt "fire in his belly" with regard to acting, he said: "I enjoy it, I still enjoy it. I love making movies, but it's more like smouldering embers now."
Gerard Butler stated that this film will be darker and more character driven than either of its previous installments, even going so far as to compare it to "Logan" (2017). He also expressed hope that this will be the final installment in the "Olympus has Fallen" series.
Nick Nolte played the role of an Ex-Vietnam War veteran in this movie. In real life, he never had a chance to go to Vietnam war due to a felony case years before. However, he felt incomplete for not being able to do so since at that time, he felt obligated to fight in Vietnam War as a young man.
All three films in the series have been distributed by different studios. FilmDistrict distributed Olympus Has Fallen (2013); Gramercy distributed London Has Fallen (2016); and Lionsgate distributed Angel Has Fallen (2019).
In Olympus Has Fallen (2013), Morgan Freeman portrayed the Speaker of the House, and in London Has Fallen (2016), he became Vice President. In between the second film and this one, his character has been elected as President of the United States. This marks the second time of Freeman as President, after he played President Tom Beck in Deep Impact (1998).
In this movie, Nick Nolte plays a Vietnam veteran who struggled with PTSD after the war. In Tropic Thunder (2008), he plays a writer who faked his military service in Vietnam, whose book is the basis for the movie being filmed. When he admits to his fraud, he is derided as "the Milli Vanilli of patriots."
Reportedly, there were no plans to have Aaron Eckhart return and play the role of the president, as the first two films are set over the course of seven years and the maximum time for a U.S. president is two terms (exactly eight years, unless if the person becomes president in the last two years of the term). So Morgan Freeman took over the role instead.
