Screen stars Katie Holmes and Demi Moore have both auditioned for roles in the upcoming movie musical produced by Harvey Weinstein.

Other names being bandied about, according to The Post, are "Chicago" stars Renée Zellweger and Catherine Zeta-Jones, who previously worked with director Rob Marshall in that highly successful stage to screen transfer.

Based on the Fellini film "8 ½," Nine premiered on Broadway in 1982, starring Raul Julia, Anita Morris and Karen Akers. The Tommy Tune-directed production won five Tony Awards, including Best Musical. In 2003 Broadway saw a revival boasting an all-star cast including Antonio Banderas, Chita Rivera, Jane Krakowski and Mary Stuart Masterson. Directed by David Leveaux and reset in the early 1960's, the revival would win two Tonys, including Best Revival.

Nine centers on Guido Contini, a heralded film director (much like Federico Fellini) who, fearing he is losing his touch, escapes to a Venetian spa for rejuvenation. Blurring the lines of fantasy and reality, the women in Contini's life swirl about him, from his mother, to his wife, to his mistress, all of whom ultimately serve as dangerous distraction and inspiration.

"Nine" is slated for a 2008 or 2009 release.
