'Avatar' No. 1 on VideoScan, Blu-ray charts

'Legion' is at No. 2 on both charts; 'Toy Story' combo debuts

"Avatar" retained its grip on the national home video sales charts the week ending May 16, beating off challenges from three new moderately successful theatrical releases.

The 20th Century Fox Home Entertainment release was the top-selling disc for the fourth consecutive week, landing at No. 1 on both the Nielsen VideoScan First Alert and the dedicated Blu-ray Disc sales charts.

The three new releases followed. The Sony Pictures fantasy "Legion" ($40.2 million), about a group of humans trapped in a diner during the Apocalypse with the Archangel Michael (Paul Bettany, the voice of Jarvis in "Iron Man 2"), debuted at No. 2 on both charts, selling 75% as many total discs as "Avatar." The Warner thriller "Edge of Darkness" ($43.3 million) debuted at No. 3, followed at No. 4 by the Lionsgate horror film "Daybreakers" ($30.1 million).

The trio of newcomers captured the top three spots on Home Media Magazine's rental chart for the week. "Edge of Darkness" finished first, with "Legion" following at No. 2 and "Daybreakers" tail-ending it at No. 3. "Avatar" was No. 4 on the rental chart, down from No. 1 the previous week.

Walt Disney Studios' newly released combo packs of "Toy Story" and "Toy Story 2" enjoyed strong sales their first week in stores, debuting at Nos. 5 and 7, respectively, on First Alert and Nos. 6 and 7 on the Blu-ray Disc chart.

And the theatrical success of "Iron Man 2" kept the original "Iron Man" in the top 10 on both the overall and Blu-ray Disc sales charts for the second consecutive week. Nearly one-third of all "Iron Man" units sold during the week were on Blu-ray Disc.
