Take this with a grain of salt but I was on IMD today and saw that Dennis Haysbert was rumored for the voice of Kilowog and John Larroquette as the voice of Tomar Re.
Haysbert as Kilowog?
John Larroquette as Tomar Re?
Haysbert is a fan favorite for many CBM characters and I think he would do good as Kilowog; I'm not very familiar with Larroquette's acting skills though. What do you guys think sound off below!
