OMG!! i think she will ROCK at this part!!! she already has the bad ass rock and roll look, but in costume and with the hair she suits the look and i think theyve picked the best actress out there to do this part!! no one else would be able to pull it off but KStew does!! i dont know what her singing voice is like cuz ive only heard her in Into the Wild and that song was kinda mellow so she obviously couldnt belt it out!! im hoping they use Kristens voice cuz im curious to see wat it sounds like!! well, only if shes capable of having that raspy, husky kinda sound!! ive listened to Joan Jett for a while to see what she sounded like and wat songs she sand and i was suprised that Britney sings one of them!!! Joan sings it WAY better and i see now with new eyes to Britneys version that she killed that song!!lol. and there are others aswell that i really like and have grown up with cuz ive found out that my parents realaly like the runaways and Joan Jett!! i learn SO much about my parents everyday that it doesnt suprise me anymore!!lol. but im liking JJ and i will quite happily get through the film because i like the music!! JJ is SO pretty!! like shes just got IT!! watever it is, shes got it!!! this films out like in 2010 smetime…is there a date or anything?
