Seminal punk rock singer Patti Smith will collaborate with Oscar-nominated screenwriter John Logan to adapt Just Kids, the bestselling memoir Smith wrote about her close relationship with photographer Robert Mapplethorpe as both came of age in their respective art forms in New York City during the ’60s and ’70s. They’ve decided to write the screenplay on spec rather than set it up with a distribution, which they certainly could have done after Just Kids won the 2010 National Book Award for Non-fiction. In fact, a lot of prestige producers wanted it. Logan most recently won a Tony Award for his play Red, about painter Mark Rothko, and he has the Ralph Fiennes-directed Coriolanus and Martin Scorsese-directed Hugo coming this fall. The book was repped by DCL Agency and Logan’s repped by CAA.
