"You're trying to protect your family. That's admirable. I'm trying to defend the nation!" Kelsey Grammer wants to save the world from another alien war after the fall of Chicago in the first clip for Transformers: Age of Extinction. His Harold Attinger has a friendly confrontation with Mark Wahlberg's Cade Yeager, who is hiding Optimus Prime in his barn. Things turn ugly when Cade accuses Attinger of trying to kill his 'little girl'. Paramount has also launched a new TV trailer featuring more action-packed footage of these robots in disguise as they fight for their freedom on American soil. If that's not enough for you, we also have a new look at Bumblebee's redesign in a new piece of promo art. Take a look as Transformers: Age of Extinction prepares to roll out later this month.
