Here are preview clips from the movie being hyped to death by Oprah Winfrey and Tyler Perry. The title of the movie is Push: Based on the Novel by Sapphire. Push is the recipient of both the Grand Jury Prize and Audience Award in the U.S. Dramatic Competition at the Sundance Film Festival.

Push stars Mo’Nique as the abusive mother of Precious Jones (Gabourey Sidibe), an illiterate, morbidly obese teenager who is raped by her father and bares him two children.

A resentful Monique feels overburdened with caring for the mildly retarded offspring of her daughter and husband. Monique does her usual outstanding job of making you feel her role.

Unfortunately, as an actress, Sidibe is kind of just there on the screen. This role which requires a liitle bit more than one-dimensional acting.

I’ve never seen a central character weight a movie down like she does (no pun intended). Sidibe says she never acted before and it certainly shows in the previews.

Oprah loves these emotional, over-the-top, innocence overcomes evil type of movies where the central character is a weakling who suddenly finds her strength by the end of the movie. Yawn.

But the surprise of the movie is Mariah Carey, who stars as a sympathetic social worker who attempts to reach out to Precious. Mariah most definitely stepped her acting game up a notch since Glitter, and we are impressed!

Paula Patton and Lenny Kravitz round out the cast of Push which was directed by Lee Daniels.
