Precious star Gabby Sidibe has revealed people mistake her film for a documentary.
The 26-year-old newcomer has wowed critics in the surprisingly uplifting tale of 16-year-old Precious, in the film of the same name, who is forced to be her mother's slave and has two children as a result of her father's abuse.
Gabby told The Guardian that not just "ordinary people" but "people who've been in the movie business 20 or 30 years" had mistaken the film for a documentary.
She said: "How dumb is that? It's got credits, it's got people in it who've acted before, it's got stars like Mariah Carey and Lenny Kravitz in it.
"Why would you think it's a documentary? It's like - Lenny Kravitz is in my documentary? And he's my nurse? And Mariah Carey is my social worker?"
The New Yorker also reveals she changed director Lee Daniel's opinion of her character, which is based on the novel Push by Sapphire.
Gabby said: "I don't think Lee got Precious at the start - he assumed what she was like. He thought bigger girls were dumb. Is he ever wrong!
"I'm a girl - so I knew what Precious was like a little bit better than him. Plus, he's from Philadelphia and I'm from Harlem, so I brought New York to this character."
