Paul Greengrass has exited the Aaron Sorkin-scripted Chicago 7. This isn’t a shock, but it was roundly denied when we called last week. Greengrass has other projects that include Memphis, the Greengrass-scripted drama about Martin Luther King Jr.’s last days and the manhunt to find his killer. While there are several MLK films percolating, this one has a script that is Oscar-caliber. That picture was originally shelved after Universal Pictures dropped out, and Greengrass instead directed Captain Phillips, the Sony drama that stars Tom Hanks and will open October 11.
