Former Spice Girl Geri Halliwell has lined up her first big-screen dramatic role in a British film titled "Therapy," and the singer is helping promote the project and met with producers at the Cannes International Film Festival on Wednesday.

Halliwell's U.K. publicist has confirmed to British media that Halliwell will star in "Therapy," a movie David Green will direct for September Films, and plans to tie in her next studio album to the film's soundtrack, according to "Variety.

For "Therapy," Halliwell has been cast in the part of Amy, a troubled London woman who enters counseling to help deal with her personal issues, only to find out that her own therapist has fallen in love with her.

Green plans to shoot the music videos for Halliwell's accompanying "Therapy" soundtrack singles during additional days build into the film's production calendar.

Halliwell's sole prior film credit came in 1997, when she appeared -- in full Ginger Spice

mode -- in her ex-group's "Spice World" vehicle.

Therapy's" final fate will be determined on how much money September Films will be able to raise for the project, which is budgeted at $15 million, but is still considered to be in the early stages of development. No one has been cast in the movie other than Halliwell.
