No current marquee actress projects intelligence onscreen better than Emily Blunt. There’s a reason the 32-year-old Brit made her breakthrough as a coolly jaded veteran of Meryl Streep’s editorial tyranny in “The Devil Wears Prada.’’ She’s a performer who was able to not only humanize but fully inhabit royal iconography in “The Young Victoria.’’ And in last year’s sci-fi standout “Edge of Tomorrow,’’ it was Blunt, not headliner Tom Cruise, whose character was more instinctively equipped to combat a relativity-warping alien threat. We all can list actors who unconvincingly fake playing cerebrally resourceful; Blunt authentically takes us back to vintage Jodie Foster. She does it again in director Denis Villeneuve’s grippingly foreboding war-on-drugs thriller “Sicario’’ (2015). Blunt plays a rising FBI agent working Arizona drug-runner territory, and recruited to assist enigmatic task force operatives Josh Brolin and Benicio Del Toro as they go after the big guns in this grisly, never-ending border skirmish. (The film’s title is Mexican lingo for hitman.) Blunt’s character is gradually shown to be idealistically naïve about the job’s dark particulars. But the sharpness of her persona is precisely what drives home the depths of Brolin and Del Toro’s protocol-shredding surreptitiousness. On a side note, in working with Villeneuve, Blunt landed herself a director with compelling smarts in his own right. You know his Jake Gyllenhaal mystery, “Prisoners,’’ but their doppelganger follow-up, “Enemy,’’ is the real mindbender. Can’t wait to see what Villeneuve does with Harrison Ford’s upcoming “Blade Runner’’ sequel. Extras: Featurettes spotlight all three “Sicario’’ leads, but you know which one we put first.

BIOPIC/ADVENTURE

THE WALK (2015)

Robert Zemeckis and Joseph Gordon-Levitt’s account of French aerialist Philippe Petit’s high-wire stroll between the Twin Towers sometimes struggles to dramatize Petit’s street-performer whimsy in a way that doesn’t feel forced. Still, Gordon-Levitt is likably energetic, and a narrative feature can do what the Oscar-winning documentary “Man on Wire’’ (2008) couldn’t: re-create the tightrope act in full, glorious motion. The dizzying visuals truly are screen magic, taking us inside Petit’s transcendent experience as he navigates his preternatural path and — agh! — reclines to commune with the heavens. See it in 3-D if you can. Extras: featurettes; deleted scenes. (Sony, $30.99; Blu-ray, $34.99; 3-D, $40.99)

THRILLER

THE VISIT (2015)

Don’t close the book on M. Night Shyamalan just yet. After a decade-long creative downward spiral the onetime suspense icon bounces back. His tale of precocious teen siblings meeting their grandparents for the first time is a relentlessly tense journey into the bizarre, with jolts that linger and some nicely played melancholy. What’s more, the movie is often surprisingly, wickedly funny, as Shyamalan eases up on the self-seriousness that hurt his storytelling even before his extended slump. Extras: alternate ending, featurette. (Universal, $29.98; Blu-ray, $34.98)
