Jessica Kiang If for any reason you’ve recently been feeling complacent about global security, international relations and oh, you know, little things like the continued existence of the species, here to herald the end of all that comes Tonje Hessen Schei and Michael Rowley’s “Praying for Armageddon,” a glossy, persuasive and increasingly alarming documentary exposing the influence of the fundamentalist Christian lobby on US politics. Loosely tracking the investigative sleuthing done by Lee Fang, a reporter at The Intercept, but also taking ample time with parachurch pastors, GOP politicians, Israeli and Palestinian observers and Mission: M25 — an evangelical biker gang who traverse the country on compact-car-sized motorcycles proselytizing and occasionally knighting one another with swords — Schei and co-director/cinematographer Rowley’s film can feel a little scattershot, as it lops off one of the Hydra heads of this malign movement, only for two or three more to sprout in its place.
