The McQuilkens is a 2015 disaster biological film.
In 1975, brothers Michael and Sean McQuilken from a Southland family travel to Sequoia National Park with Mary and Jeff Sutton and Margie Warthen, only to end up in a hair-raising and imminent catastrophe of their lives.

Principal photography began in the summer of 2014; the Sequoia National Park was redesigned to represent it in the 1970s. The climax taking place at Moro Rock was shot on location and even on a soundstage where practical effects could be done. Lightning was recreated in CGI.
Rated PG-13 for disturbing thematic material involving a natural disaster, violent images and for language.
