Three new releases snagged the three top spots on the national home video sales charts for the week ending March 1, led by Walt Disney Studios’ “Big Hero 6,” the animated superhero adventure about the special bond that develops between an inflatable robot and a human prodigy that earned $220.9 million in theaters.

“Big Hero 6,” the 54th film in the Walt Disney Animated Classics line, easily debuted at No. 1 on both the Nielsen VideoScan First Alert chart, which tracks total disc sales, and Nielsen’s dedicated Blu-ray Disc chart.

The film, which according to Nielsen generated 58% of its total sales from Blu-ray Disc combo packs, sold more than 10 times as many discs as its nearest competitor, the No. 2-debuting “Horrible Bosses 2,” from Warner Bros.

“Sons of Anarchy: The Final Season,” from 20th Century Fox, bowed at No. 3, while the prior week’s top seller, HBO’s fourth-season set of “Game of Thrones,” slipped to No. 4.

Rounding out the top five on First Alert was Universal Pictures’ “Dumb and Dumber To,” the sequel to the 1994 comedy with Jim Carrey and Jeff Daniels.

On the Blu-ray Disc chart, “Game of Thrones” finished the week at No. 2, with 20th Century Fox’s “Birdman” – buoyed by its best picture Oscar win – moved up two spots to No. 3.

Sony Pictures’ “The Interview” slid one spot to No. 4, while “Horrible Bosses 2” debuted at No. 5.

“Horrible Bosses” generated just 18% of its first-week sales from Blu-ray Disc, compared to 22% for “Sons of Anarchy” – surprisingly low totals.

On Home Media Magazine’s rental chart for the week, Universal Pictures’ “Lucy” remained at No. 1 for the second consecutive week, while 20th Century Fox’s “Gone Girl” moved back up to No. 2.

Twentieth Century Fox’s “The Book of Life” shot up to No. 3 now that its 28-day holdback from Netflix and Redbox is over, while two indies took over the last two spots in the top five: Anchor Bay with “St. Vincent” at No. 4 and Lionsgate with “John Wick” at No. 5.

Big Hero 6” debuted at No. 6.
