New 'Transformers: The Last Knight' Poster 'Rethinks' Optimus Prime

2017 will be the year that our most beloved heroes turn on us: from Dom Toretto flipping his family’s cars into each other to Optimus Prime trying to murder Bumblebee, it’s not looking good for the good guys. The latest poster for Transformers: The Last Knight makes no secret of Optimus’ new evil status. It tells us, “Rethink Your Heroes,” over an image of the Autobot holding a massive sword featured in promo art before while his eyes glow that all-too-familiar Decepticon blue.
