Jonathan Demme on "Ricki and the Flash"

The Daily Beast recently interviewed director Jonathan Demme and he had this to say about his upcoming film with Meryl:

 Now, I’m in heightened pre-production on a feature film, Ricki and the Flash, which we’re going to start shooting on Oct. 1. It’s a great script by Diablo Cody, and Meryl Streep, Kevin Kline, and Mamie Gummer are in the cast. It’s a rock ’n’ roll driven family drama/comedy.

So Meryl plays a rocker? Who did you model her character on.  

Meryl plays Ricki and she’s the rocker. Kevin is the ex—the abandoned husband who lost Ricki to rock ’n’ roll. In our story, they come back together again under grave family circumstances. There’s another part we’re looking to cast of the guitarist who really wants to be Meryl’s boyfriend. Meryl, who is as we know a terrific singer, is a rock ’n’ roller. She loves rock ’n’ roll, and is taking a very personally-crafted approach to Ricki. Ricki’s of a generation of people like Joan Jett and Chrissie Hynde, but I think this is going to be a very unique act.

Well, I guess we can consider that concrete verification that Mamie Gummer is in fact going to play Meryl's daughter.  We also get a little more specific info about the kind of persona Meryl may try to convey based on Demme's Joan Jett reference.  Very intrigued to see what our girl delivers.  Ricki and the Flash is set for a June 26th release next year.
