Oscar-winning actress Halle Berry (shown here at last week’s 14th Annual Hollywood Awards Gala), will soon grace the big screen again when her new film Frankie & Alice hits theaters December 17, 2010.

According to ComingSoon.net, Frankie & Alice, both starring and produced by Berry, “is a moving psychological drama based on the harrowing true story of Frankie Murdoch (Berry), a woman suffering with multiple personality disorder in early 1970s Los Angeles.”

IMDB thickens the plot by adding Murdoch “struggles to remain her true self and not give in to her racist alter-personality.”

Note, this isn’t Berry’s first portrayal of a character dealing with mental health issues. Back in 1995, she played Khaila Richards, a young mother who loses custody of her child due to drug addiction in Losing Isaiah.

Of Frankie & Alice, Berry says:

Bringing this story to the big screen has been a challenging, yet very satisfying, filmmaking experience. Her struggles with mental illness came at a time when the medical community and the public were still grappling with the veracity of multiple personality disorder, and I approached this role with feelings of humility, yet great responsibility.

Frankie & Alice was actually on the 2009 Academy Awards Reminder List (…?), but it showed at Cannes back in May 2010 and concrete, this-is-actually-going-to-happen release dates were only just recently announced.

Deadline Hollywood’s Pete Hammond reports the movie’s December 17 release applies to New York and Los Angeles, and its regular theatrical release is set for February 4, 2011. Some writers, such as EW.com’s Dave Karger of Oscar Watch, believe this Release Date Shuffle puts Berry in a good position to “try to shake up this season’s Best Actress race” at the Oscars (although he doesn’t think there’s as good a chance of that as there was for Jeff Bridges, who swooped in at the last minute and won last year for Crazy Heart).

Confusing release dates and Oscar potential aside, do you think you’ll be in theaters this winter for Frankie & Alice?
