“London Has Fallen” (*** out of four) was a fun follow-up to 2013’s “Olympus Has Fallen” with the President Of The United States (Aaron Eckhart) and his dedicated Secret Service agent (Gerard Butler) in London attending the funeral of the Prime Minister with several world leaders when they are besieged by an international terrorist intent on murdering the President on national television. Packed with enough action, stunts, and spectacular special effects to give action fans and fans of the original their money’s worth. Can “NY Has Fallen” be next?
