Ryan Coogler’s "Fruitvale Station" is about a month away from hitting theaters nationwide in the United States. The film, a Sundance favorite, has already gotten rave reviews based on its gripping portrayal of the last day of Oscar Grant’s life before he was gunned down by former BART police officer Johannes Mehserle. That’s not an easy talk for any filmmaker, but Coogler, the film’s writer and diretor, and Spencer, who plays Grant’s mother Wanda, were able to prepare for their roles by speaking with surviving members of Grant’s family. Watch them talk about the experience in the interview that’s above.
