Variety is reporting that Kelsey Grammer (X-Men: The Last Stand, Frasier) has been cast in Transformers 4. Grammer will star opposite of Mark Wahlberg, Jack Reynor, and Nicola Peltz. At this juncture it is only known that Grammer will play the villain. Whether that is a human or a Transformer remains to be seen. Rumors of the planet devouring Unicorn have been circulating and Grammer certainly could supply the perfect voice for the character. If that were indeed the case, he would be voicing a Transformer previously done by the Orson Wells.
Michael Bay (Pain & Gain) will return to direct Transformers 4 with a script penned by Ehren Krueger (Transformers: Dark of the Moon).
Transformers 4 is slated for June 27, 2014.
