Don't know, don't know, sounds OK, know but not feeling it for him, ohgawdplzno, and can't place. I think it should be (in the same order) Chris Pratt, Scott Bakula, Emma Stone, Liam Neeson, Charlie Day and Zachary Levi. I have RDJ as Lewa because of personality, lol. Peter Cullen is the voice of Optimus Prime. So here's a new version.... Chris Pratt, Vin Diesel, Zoe Saldana, Arnold Schwarzenegger, Nolan North, Peter Cullen. Vin Diesel? As the big wise guy? No. Just... no. You want an action hero as Onua? My vote goes to Danny Trejo. He's the only guy who doesn't fit the wise guy archetype that I'd like as Onua (though the accent might be a little thick.) Zoe Saldana? She's the green chick in Guardians of the Galaxy, right? Nah... She's too... not Gali. Ahnald Swazzenegger? Da Turminatah? Ahs Kopaka? Ha. Ha. Ha. You funny. Nolan North as Lewa? Okay... I like Charlie Day more, but I suppose we can substitute Benny's SPACESHIP! for the Space Core's proclamation of SPACE! SPACE! SSSPPPAAACCCEEE! if we so desired. And Optimus Prime as Tahu? To be honest, I've always seen Tahu as more the awkward hero, an unlikely hero, the underdog. Having Optimus Prime voice him... uh... Ok... I forgot to mention the Protectors. Of course, the Protector of Fire must be Morgan Freeman, the PoW could be Meryl Streep, the PoA could be Nolan North, the PoI might work with Garry Chalk (Colonel Chekov from SG-1 and Optimus Prime from... whereever he voiced Optimus Prime), the PoS could be... um... that guy... and the PoE could be Patrick Stewart. If they wanted Ekimu in the film, perhaps Michael Dorn could voice him like he did Mata Nui, and Makuta could be played by Cliff Simon (Baal.) You dunno Steve Blum, but he voiced Starscream in Transformers Prime and Tank Dempsey in CoD WaW Nazi Zombies, CoD Black Ops Zombies, and CoD: BO2 Zombies. Nolan North voiced Smokescreen from Transformers Prime, Nathan Drake from Uncharted, and Edward Richtofen from CoD Zombies. Fred Tatasciore voiced Nikolai and Dr Maxis from CoD Zombies, as well as Tuma from TLR. Steve Blum actually fits Kopaka, now that I think of his Dempsey voice. Kate Beckinsale might be a good fit for Gali. David Kaye as Tahu, perhaps? Peter Cullen for Onua, Nolan North as Pohatu, Chris Pratt as Lewa. How does that sound?
