Arcade Fire have lent one of their tunes to a trailer for the upcoming Brad Pitt movie “The Curious Case Of Benjamin Button.”

“My Body Is A Cage,” the closer off last year’s “Neon Bible,” features prominently in the TV spot for the David Fincher-directed drama, which hits theatres Dec. 25.

Also starring Cate Blanchett, the movie is based on a 1922 short story by F. Scott Fitzgerald and tells the story of a man who is born in his eighties and ages backwards.

The National Board of Review launched the movie awards season Thursday by naming Fincher (”Panic Room,” “Fight Club”) best director of the year for “Benjamin Button.”

In other Arcade Fire news, the Montreal band is contributing their rare track “When Lenin Was Little” to the charity compilation “Dark Was The Night,” which will be released in February.

They are one of several Canadian acts featured on the compilation; others include Buck 65, Feist, Kevin Drew and The New Pornographers.

The 32-track album, produced by The National’s Aaron and Bryce Dessner, will benefit the Red Hot Organization, which is dedicated to raising funds and awareness for HIV and AIDS.
