Kristen Stewart: Bella is Manic-Depressive

Kristen Stewart and costar Dakota Fanning continue to film on The Runaways on Monday night (July 27) in Los Angeles.

The 19-year-old actress recently dished at the 2009 San Diego Comic Con about her other flick, New Moon.

Kristen shared about her character, Bella, saying, “This movie’s not about discovery or falling in love, which is sort of an intense emotion, but this is like low, and there are high points for it too and she’s a manic-depressive, basically.

She continued, “It was just sort of heavier. There was more to think about. It’s a more mature part strictly because she’s older. She had more to deal with.”

Also pictured below is actor Michael Shannon, who plays The Runaways manager Kim Fowley in the biopic.
