David Oyelowo, Freddie Prinze Jr., Vanessa Marshall, Taylor Gray and Steven Jay Blum are all in negotiations to voice the leads in the upcoming CG animated "Star Wars: Rebels" series for Lucasfilm Animation.
All that's known about the story is that it's set in the time period between the two trilogies, a time when the Empire expanded its reach.
Simon Kinberg, Dave Filoni, and Greg Weisman are executive producing. The series premieres Fall 2014 on Disney XD.
