Kim Kardashian, an object of study? If you're Emma Watson, then yes.

According to "Bling Ring" director Sofia Coppola, British actress Watson marathoned "Keeping Up With the Kardashians" in preparation for her role in the film, now in theaters.

"I think she watched a lot of 'Kardashians' to get a Calabasas accent," Coppola dished to E! News at the Women in Film Crystal + Lucy Awards on June 12. "And she watched 'Pretty Wild' and she immersed herself into all of that."

Watson's "Bling Ring" character, Nicki, is based on Alexis Neiers, one of the stars of "Pretty Wild," an E! reality series that aired after the Bling Ring's illegal exploits came to light.

"I think she did an incredible job with the accent, it's really specific," Coppola gushed. "She's such a Californian, it's very Calabasas."

Reality TV -- good for more than just guilty-pleasure viewing and 15 minutes of fame.
