The mongrel progeny of horror and comedy is not always a thing of beauty, but “Get Duked!” — a darkly funny lark about four city lads on a camping competition in the Scottish Highlands who are being stalked by an upper-class psychopath — comes close to nailing the unstable DNA of sickness mixed with humor. Taking its title from the Duke of Edinburgh program, in which urban teens are exposed to orienteering, foraging and teamwork in the great outdoors, the film follows the protagonists (Samuel Bottomley, Viraj Juneja, Rian Gordan and Lewis Gribben) as they are forced to use their (dim) wits to elude a masked man with a rifle (Eddie Izzard) who is trying to “cull the herd” of undesirable blood. There’s a moment or two when the film strays over the line, but mostly it stays just this side of reality, with jokes about psychedelic rabbit poop, bumbling cops and the (presumably) dead body of the youngsters’ chaperone (Jonathan Aris). It’s silly stuff, never genuinely scary and a pleasant escape from the real world — courtesy of some gorgeous scenery. R. Available on Amazon Prime Video. Contains drug use, coarse language throughout, including sexual references, some violence and bloody images. 86 minutes.

The documentary “Class Action Park” offers an (at first amusing) oral history of Action Park, a notoriously unsafe New Jersey water park that operated from 1978 to 1996 and whose reputation for injury included lacerations, concussions, missing teeth, dislocated joints, a broken back the loss of a finger — and death. That history lends the film its title — taken from the one of the park’s jokey nicknames (it was also known as Traction Park). Through reminiscences from former park guests (including actors Chris Gethard and Alison Becker), past employees and journalists who covered its many run-ins with courts, a picture emerges of a toxic blend of lax safety standards and thrill-seeking teens. For much of the film, the tone is all weren’t-we-crazy? — until, of course, the film shifts to discussion one of the park’s most grisly deaths. What starts out as a darkly comic trip down Memory Lane gradually morphs into a meditation on how dangerous growing up used to be. Unrated. Available on HBO Max. 89 minutes.

The faith-based drama “Fatima” tells the true story of Lúcia dos Santos (Stephanie Gill of “Terminator: Dark Fate”), a 10-year-old Portuguese peasant girl who, in 1917, reported witnessing apparitions of the Virgin Mary (Joana Ribeiro), along with two other children. Told via the reminiscences of an older Lúcia (Sonia Braga) — now a nun — during an interview with a skeptical academic (Harvey Keitel), the film presents the girl’s tale in the context of gentle pushback. This mostly comes courtesy of the town’s no-nonsense mayor (Goran Visnjic of “ER”) and the Catholic Church itself, personified by a local priest (Joaquim de Almeida) and his embarrassed superiors. The cast is strong, most notably Lúcia Moniz — remember her in “Love Actually”? — as the little girl’s slightly overwhelmed mother. PG-13. Available on various streaming platforms. Contains some strong violence and disturbing images. 113 minutes.
