Actress Rooney Mara has warned her peers not to fill up with food when shooting diner scenes in director David Fincher's films - because the moviemaker likes to revisit takes and some stars could end up eating until they're sick.
The young star learned an unhealthy lesson during a pizza scene in new thriller The Girl With The Dragon Tattoo.
She explains, "You're doing it take after take... I was eating pizza in one scene, and I literally ate, like, 20 pieces."
And she also urges young stars who are called on to smoke in Fincher's films to limit their intake of nicotine.
Mara explains, "I had been smoking a lot for the movie and then spent three days just running non-stop. You never want to smoke or eat in a David Fincher movie."
