Author Jonathan Lethem sold movie rights to two of his books which never got made. Disappointed, he started the Promiscuous Materials Project where he publishes short stories online and invites filmmakers and playwrights to adapt them. He asks for only a $1 fee and that he get credit as author of the source material. It’s gotten results too; Filmmakers are now at work on adaptations of his stories. Smart move by Lethem to realize letting go of his copyrights is smarter than protecting them at all costs. If a movie or play based on his material takes off, so will his book sales.
