New movies to stream this week: 'Wild Mountain Thyme,' 'The Stand In' and more

If you can believe Emily Blunt and Jamie Dornan as plain Irish farm folk — living on side-by-side parcels of land and both too shy and/or tetched to realize that they (and each other) are Hollywood-hot under all that dung-stained flannel and denim — then “Wild Mountain Thyme” has something to sell you. What it’s selling is a slightly gloomy, slightly swoony Hibernian rom-com by John Patrick Shanley, based on his 2014 play “Outside Mullingar.” It’s not terrible. It’s just, like its main characters, somewhat odd. Dornan’s Anthony refers to himself as having a “tiny-ness” in his head. And you’ll wait the whole movie to find out what that silly thing means. Just as you’ll wait the whole movie for him to realize that he and Blunt’s besotted Rosemary are meant for each other. (Meanwhile, she briefly gets so fed up with waiting for Anthony to kiss her, faith and begorrah, that she toys with running off with Anthony’s crass American cousin, played by Jon Hamm.) I’ve seen a million romantic comedies with this exact same setup, and they all work the same way. But this one is so frustrating. That said, Shanley’s screenplay is kind of funny, in a dismal, doomed Irish way. (There are several deaths in it: more than you typically find in your American romantic comedy, but probably less than you’d see in the average Irish drama.) It has a peaty lyricism to it; it’s poetry, to be sure, but smelling of barn muck, not, as the title suggests, flowering herbs. PG-13. Available on various streaming platforms; also showing at the Cinema Arts Theatre. Contains some mature thematic elements and suggestive comments. 102 minutes.• • •Also streaming: • The documentary “Alabama Snake” investigates a woman’s 1991 accusation of attempted murder by her husband, snake-handling Pentecostal preacher Glenn Summerford. TV-MA. Available on HBO and HBO Max. 85 minutes.• Joe Mangiello (“Magic Mike”) plays an alcoholic who claims to be a traveler from another dimension who lost his superpowers when he came to Earth in the action-adventure film “Archenemy.” Although the film is a little too heavy-handed with the stale superhero tropes, Flickering Myth calls the movie a “fascinating blend of live-action and animation.” Unrated. Available at afisilver.afi.com. 90 minutes.• From documentarian Ryan White (“Ask Dr. Ruth”), “Assassins” takes a look at the 2017 airport assassination of the half brother of North Korea’s leader Kim Jong Un, by two women.

In English, Indonesian, Vietnamese and Malay with subtitles. 104 minutes.• During a winter dive, a woman becomes trapped on the ocean floor by falling rocks in “Breaking Surface.” According to Bloody Disgusting, the film from Swedish writer-director Joachim Heden is “one of the most intense and propulsive survival thrillers in recent memory.” Unrated. Available at virtualavalon.org. In Swedish and Norwegian with subtitles. 82 minutes.• Just when you thought you’d seen every possible member of the Skarsgard acting dynasty, another one pops up: Valter Skarsgard, the 25-year-old son of Stellan Skarsgard and the youngest brother of thespians Alexander, Gustaf and Bill Skarsgard, stars in “Don’t Click,” a horror film about a young man who discovers a porn website that turns out to be a portal to a diabolical world.
