HQ: Peter Travers Happy 24th Birthday to Kristen Stewart. Free of the Twilight noose, KStew has been making lots of film choices that put her in the indie sphere where she can spread her wings. At Sundance, in Camp X-Ray, she did powerful, textured work as a military prison guard at Guantanamo. Next up is American Ultra with Jesse Eisenberg. For big bucks, she’s the new face of Chanel. I think the outlook is bright for the birthday girl. You?
