Floria Sigismondi

I've already gotten to tell you what I think about rock biopic The Runaways, with Kristen Stewart and Dakota Fanning, but now it's time to hear from the stars and the others behind the scenes of the movie. Pop chatted up Kristen Stewart on the red carpet in NYC, but we also have some choice words from its inspiration Joan Jett, costar Michael Shannon, and director Floria Sigismondi.

• Joan Jett on the message of the film: Ultimately, to follow your dreams. That good old cliché of following your dreams, because I really feel that people beat down other people’s dreams constantly. I see it a lot with writers, when I talk to them about this. I guess a lot of writers must be told, "You’ll never make money that way, get a real job!" A lot of writers want to write . . . To me, I just think it’s really important to try and follow your dream. And if for some reason life takes you a different way, then at least you made an attempt.
• Joan on first meeting Kristen: I met her last New Year’s Eve. She came up to see a gig and I kind of just dumped on her about The Runaways for several hours and asked her if she was going to cut her hair. She said yes, and I had great faith that she was going to be able to pull this off because she seemed very dedicated and genuine and authentic. We had a few weeks before filming started to spend some time, and she picked my brain.

Kristen Stewart gives a hug to the director of The Runaways, whose top busted open on stage at SXSW last night. Katherine Heigl had a wardrobe malfunction of her own when her dress strap snapped during her speech at ShoWest, and Audrina Patridge sends her well-wishes to Jason Wahler. Watch the PopSugar Rush Weekend Edition!

Dakota Fanning and Kristen Stewart joined The Runaways director Floria Sigismondi last night for a screening in Austin as a part of the SXSW Film Festival. Dakota and Kristen have been all over the country promoting their film with a premiere in LA last week before Wednesday night's big NYC event with Joan Jett and Cherie Currie, where both of the young stars opened up to us about their work on the movie. Their tour will come to a close with the project's opening today, and we'll see if Kristen and Dakota fare better at the box office than Robert Pattinson's recent non-Twilight effort — check out what Buzz thinks of Dakota and Kristen's turns as teenage rock stars.

Kristen Stewart and Dakota Fanning caused minor pandemonium last night when they arrived at NYC's Landmark Sunshine theater for their NYC premiere of The Runaways, presented by Tommy Hilfiger and Quintessentially. We had a first look at Kristen showing some leg in her Pucci minidress, and Dakota also looked great in her Valentino. We caught up with Dakota at Tuesday's press junket, where she opened up about the process of channeling Cherie Currie. Yesterday, she was happy to talk about all the fun she and her female costars had on set and said Kristen's become "one of my best friends." Kristen, meanwhile, revealed she occasionally gets tired of all the prep it takes to get ready for events. She also weighed in on the Breaking Dawn director drama and said she's excited to see who they pick, and once press for this film has wrapped, she actually has a vacation coming! Exclusive video from the exciting night coming up so stay tuned for PopSugar Rush.

Kristen Stewart and Dakota Fanning kept the celebrations going last night as they went from their big LA premiere of The Runaways to the afterparty at the Cabana Club. Taylor Lautner stopped to sign a few autographs for fans before joining the girls, while Kristen changed into something more comfortable just as she did between Robert Pattinson's recent Remember Me screening and bash. Joan Jett kept the girls laughing in the VIP section, after Dakota and Kristen had done a long day of press for their movie. A kiss between Kristen and Dakota has lots of people interested, but for Ms. Stewart, it was no big deal. "It was cool. I didn't mind it," she said. "The way that it happens in the script is so just a sort of moment in time and fun and natural and sort of impulsive."
