 This screen adaptation stars Meryl Streep as Miranda Priestly, a powerful fashion magazine editor, and Anne Hathaway as Andrea ("Andy") Sachs, a college graduate who goes to New York City and lands a job as Priestly's co-assistant.
 Emily Blunt and Stanley Tucci co-star as co-assistant Emily Charlton and art director Nigel, respectively.

 The album is a follow up to The Devil Wears Prada's 2009 album, "With Roots Above and Branches Below".
 Much like their previous efforts the album's lyrics were penned by lead vocalist Mike Hranica, whose lyrical direction focused on anti-idolatry concepts.
 The band's musical style changed after the success of the "Zombie EP", this led to, what Hranica described as; fusing the melodic elements of their previous studio albums with the ferocity of "Zombie".
