Los angeles (BFT): Kristen Stewart has said sometimes it feels like her roles choose her, not the other way around. In her latest film, Still Alice, the Twilight actress appears opposite Julianne Moore as the daughter of a linguistics professor who is shocked to be diagnosed with early onset Alzheimer’s disease. Kristen revealed at the premiere of the film, at the AFI Fest in Los Angeles: ‘To commit to the responsibility of bringing a character to life. I know it sounds funny to think about it in those terms, but unless there is just an undeniable urge, an insurmountable...’I would have put my whole life on the fact I can play this part’ - it’s not a responsible thing to take the part.”
