We were curious to see how the mythology-redefining “Man of Steel” (2013) would embrace its superheroic legacy on DVD. Would this Henry Cavill incarnation be given the megaset treatment, packaged together with Christopher Reeve’s Superman outings and the 2006 soft-continuity sequel, “Superman Returns”? Not too surprisingly, the answer is no. Rather than looking to the past, the hero’s current screen handlers seem intent on continuing to stand apart and look ahead (at tossing Wonder Woman into the sequel mix along with Ben Affleck’s Batman, if you believe last week’s fan chatter). Bonus materials on the disc do include a retrospective look at the evolution of the character, as well as his friends and foes (including Michael Shannon’s updated General Zod, now as much a denizen of moral gray areas as the Phantom Zone). Still, the focus is squarely on the new movie’s production in a collection of branching Blu-ray segments hosted by hipster director and dude-of-the-hour Zack Snyder. Critics may snicker, but for someone whose comics-adaptation filmography already included “300” and “Watchmen,” Snyder at times seemed to have been almost a sidelight in the movie’s hype ramp-up: Warner is thrilled to announce that we’re handing the “Superman” keys to producer and “Dark Knight” genius Christopher Nolan. And, oh, yeah — Zack Snyder is driving. Get a fresh look at Snyder’s persuasive enthusiasm here. Also get a look at the Superman-ly training regimen that sculpted a kid once called “Fat Cavill” into a Man of Steel. (Warner, $28.98; Blu-ray, $35.99; 3-D, $44.95)
JFK (ULTIMATE COLLECTOR’S EDITION) (1991)
With the 50th anniversary of the Kennedy assassination upon us, studio vault-minders deliver an elaborate Blu-ray reissue of Oliver Stone’s cinematic conspiracy theory, starring Kevin Costner as intrepid D.A. Jim Garrison. The package includes three documentaries: “JFK: To the Brink,” from Stone’s Showtime series, “The Untold History of the United States”; “JFK Remembered: 50 Years Later”; and the vintage presidency retrospective “John F. Kennedy: Years of Lightning, Day of Drums” (1965), narrated by Gregory Peck. Kennedy’s combat heroism is recalled in another supplement, the WWII drama “PT 109” (1963), with Cliff Robertson as the young naval officer destined to become commander in chief. (Warner, $59.99)
A garden-trolling snail (Ryan Reynolds) dreams of Indy 500 glory — an order only slightly taller than trying to put a fresh spin on animated racing and micro-scale action after “Cars” and a host of adventure-in-the-grass ’toons. But “Turbo” makes an entertaining go of it by liberally borrowing from the “Fast & Furious” franchise and sticking a slime trail onto “Rocky” for the rest. Unfairly seems to have gotten lumped together with “R.I.P.D.” as part of a summer of duds for Reynolds. Extras: Character drawing tutorials and “Shell Creator” activity; preview of the upcoming Netflix spinoff series, “Turbo: F.A.S.T.” (DreamWorks, $29.98; Blu-ray, $39.99; 3-D, $48.99)Tom Russo can be reached at email@example.com.
