Paramount Pictures wants potential Transformers: Age of Extinction viewers to know at least three things about director Michael Bay's film: It features Mark Wahlberg discovering Optimus Prime; humans need Transformers to protect them from an invasion; giant robots fighting dinosaur robots always looks cool.

Three new television spots for the action movie give us the first audio snippets of Kelsey Grammer's Harold Attinger, who's been absent from the onslaught of promotional materials. He joins Wahlberg, Nicola Peltz, T.J. Miller, Jack Reynor and the voice talents of Peter Cullen, John Goodman and Ken Watanabe in the fourth installment of the blockbuster franchise.

Transformers: Age of Extinction opens on June 27.
