Box Office Bomb: Budget, $110 million. Box office, $87,242,834 (domestic), $296,394,640 (worldwide). The film version of Ransom Riggs's novel fell short of its budget domestically but got by thanks to its international takings. Between its reception and adaptation changes, it's unknown if the novel's sequels will get adapted.
California Doubling: The interior of Miss Peregrine's house is in Belgium. Cornwall also doubled for Wales in a couple of scenes.
English actor Asa Butterfield puts on an American accent as Jake. Lampshaded when he first arrives in 1943 and one of the locals mistakes him for a spy, saying "his accent's not very good".
Irish actor Chris O'Dowd as Jake's equally American father Franklin.
Fake Brit: Eva Green once again downplays her French accent to play an apparently British character.
