Xmas DVD Sales Showdown: 'Mamma Mia' Dethrones 'The Dark Knight'

“The Dark Knight” might be near invincible, but at Christmas time when the sales battles go head to head on DVD, the shadowy Gotham figure has been toppled by a bunch of middle aged women under the aegis of Swedish pop stars.

Yup, “Mamma Mia” has dethroned the ‘Knight’ on the Nielsen VideoScan First Alert sales chart landing at number 1 for the week ending Dec. 21, according to The Hollywood Reporter.

Christopher Nolan’s Batman sequel will remain the top-selling DVD of the year, but for this week, ‘Mia’ outsold the comic book noir, though TDK’ did as much business in its second week as the musical comedy did.

“The Mummy: Tomb of the Dragon Emperor,” also bumped ‘Dark Knight’ to the second-place spot on Home Media Magazine’s rental chart for the week. Whether there is a rise in female teen assaults next week due to upset Batman obsessives remains to be seen, but “Mamma Mia” pre-teens and Abba enthusiasts are being strongly encouraged to leave all pins, T-shirts and promotional clothing or paraphernalia at home for the next few weeks.
