Check Out Clip of Mariah Carey In 'Push'

Everyone's been talking about how good Mariah Carey is in 'Push: Based on the Novel by Sapphire', which took home three awards from this year's 'Sundance Film Festival,' including the Grand Jury Prize and the Audience Award.

Not only has the film, which is being championed by Oprah Winfrey and Tyler Perry, received rave reviews, but 'Variety' described her acting as "pitch-perfect".

Since she had a lead role in the film 'Glitter' in 2001, which was heavily panned by critics, Carey has slowly been building her repertoire with roles in the independent film 'WiseGirls' (2002), and a cameo in Adam Sandler's 2008 film 'You Don't Mess with the Zohan', playing herself.

In 'Push,' she plays a passionate social worker. Also starring in the film are Mo'Nique, Paula Patton, Lenny Kravitz, Kimberly Russell and Sherri Shepherd. Newcomer Gabourey Sidibe plays the lead.

Directed by Lee Daniels, the film tells the redemptive story of Precious Jones, a young girl in Harlem struggling to overcome tremendous obstacles and discover her own voice.

Verbally and sexually abused by her family, her troubles lead to problems in school. Precious has no friends, no money, two kids (from her father), and she's illiterate. After being accepted into an alternative school, one of her teachers (Patton) helps her find new direction in life. Along her journey, she comes across a concerned social worker (Carey) and a nurse (Kravitz) who show her incredible kindness.

In March 2009, Carey's film 'Tennessee' arrives in theaters.
