Rosario Dawson has talked about Parts Per Billion, an upcoming ensemble drama which also stars Twilight star Robert Pattinson.

"[The script features several] different storylines that are going on,” said Dawson to MTV. “I don’t have a relationship to him in the film. So we never meet. But we’re all within the same group of people, and the same city of people, that are responding to a life-threatening situation."

The film also stars Olivia Thirlby and Dennis Hopper.
