Shield your Macbook screens, it's time for a nerdgasm. Star Trek's Spock himself, Leonard Nimoy, is coming out of his recently announced acting retirement to voice Optimus Prime's older brother and predecessor, Sentinel Prime, in Transformers 3: Dark Of The Moon. I don't really understand how a robot can have a brother, but this is still really good news for people who care about the Transformers franchise. Seriously, as someone who half watched the first one, can you tell me how robots can have brothers? Is it because they are aliens, and their concept of family doesn't apply to us? Look, I'm sorry, I'm being really insensitive to nerds right now. I think Leonard Nimoy is cool, and just because I think it's weird or outdated or post-ironic to give a shit about the THIRD Transformers movie, doesn't mean you can't. In fact, please do care. It'll be a lot less shocking when the movie goes on to gross 5 billion dollars. (MTV)
