First look at Kelsey Grammer as the bad guy in "Transformers 4" is offered by Chicago Tribune. The five-time Emmy Award winner was spotted filming at Chicago's Millenium Park on Sunday, August 25. Taking a break in-between the sequences, the 58-year-old star, looking dapper in black suit with white shirt and striped tie, used a personal fan to keep him cool under the blazing sun.

On Wednesday, it was time for Mark Wahlberg and T.J. Miller to leap into action. The leading actor and his co-star filmed their scenes, described as "dusty," in the uptown neighborhood of Chicago, that Michael Bay has turned into Texas. The Uptown Theatre, where they filmed scenes indoors, was decorated with posters that read "SXSW Music Fest Jun 8, 2002."

Grammer is featured as Harold Attinger, who will face off against Wahlberg's character. The latter will team up with Jack Reynor, a new face in the franchise besides Nicola Peltz, Stanley Tucci, Sophia Myles, Victoria Summer, who was seen filming her part on the same day as Grammer, and more.

Said to be darker than its predecessors, "Transformers 4" is scheduled to open in the U.S. June 2014.
