The musical would focus on three rival performers (Diaz, Witherspoon, Paltrow) who each had one successful single in the '90s; down on their luck, the trio joins forces as a way to get back into the spotlight. The idea is that Samberg and his Lonely Island troupe (Akiva Schaffer and Jorma Taccone) would write original music for "Wonders," while Beyonce's role is currently unknown. (If you like to believe Internet commenters, one wrote on Deadline.com that Blue Ivy's mama would play the woman who actually sang the three one-hits released by Diaz, Witherspoon and Paltrow's characters.)
While Paltrow and Witherspoon are noted for their strong singing voices (see Paltrow's work on "Glee" and in "Country Strong" and Witherspoon's role in "Walk the Line"), Diaz has been known throughout her career for a lack of vocal prowess. In "My Best Friend's Wedding," she famously shrieked through a karaoke version of "I Just Don't Know What To Do With Myself" and in 2008 the actress told the Associated Press that she found performing live on stage "impossible."
Sony picked up Murphy's pitch for the comedy, though the studio hasn't confirmed deals with anyone just yet. Murphy previously worked with Paltrow on "Glee," and is busy with his adaptation of "The Normal Heart." Let's hope hell doesn't freeze over before this cuckoo-bananas production gets off the ground!
