After all, the shaky-cam auteur behind the last two Bourne installments also helmed 2006’s tense 9/11 film United 93. Now Greengrass may be making his next movie about the final days of Martin Luther King’s life before his assassination outside of a motel in Memphis on April 4, 1968. According to New York magazine, Greengrass has penned the script for Memphis, which is based on his own research into the slain civil rights leader. Greengrass’ agents at CAA issued a “no comment” about the MLK project. Meanwhile, producer Scott Rudin told EW exclusively that he recently had conversations with Greengrass about helming his in-the-works 3-D Cleopatra epic, which would star Angelina Jolie as the Queen of the Nile.
