New TV Spot for “Transformers 4: Age of Extinction” Plus, David Letterman Exclusive Transformers 4 Clip!

We have two all new “Transformers 4: Age of Extinction” clips for you! The first one we have for you has run time of 30 seconds and was uploaded yesterday by Comic Book Movie.

The second one is over at the OnFormers Facebook Page. It’s a short exclusive clip of the movie from the interview with Kelsey Grammer on David Letterman. The audio in this video is of very dismal quality when it comes to the audio.
