Having already tackled weighty subjects like the Iraq war with Green Zone, as well as Bloody Sunday and United 93, acclaimed director Paul Greengrass is set to film the events leading up to the assassination of civil rights leader Martin Luther King in a film called Memphis, reports Empire Online. Greengrass has proven to be one of the most visceral filmmakers in Hollywood in recent years and his style would seem to suit a story like this. It must be emphasised though that none of this is official yet and we're not even sure if this project will ever see the light of day. Also, is Will Smith available? We're sure Martin Lawrence is, but let's not go there.
