Mark Wahlberg leads a revamped cast, which also includes Stanley Tucci, Jack Reynor and Nicola Peltz
Grammer, who recently won a Golden Globe for his turn as a scheming politician (is there any other kind?) on Starz's "Boss," will play a counter-intelligence operative who figures prominently in the plot.
The "Transformers" franchise could use a flesh-and-blood bad guy to root against, so let's hope Grammer is able to showcase the cackling menace he brought to the villainous role of Sideshow Bob on "The Simpsons."
Deadline broke the news of Grammer's casting in "Transformers 4."
