Deadline is reporting that Kelsey Grammer (Boss, Frasier) has been cast as the human bad guy for Transformers 4. According to the site he is playing "Harold Attinger, a counter intelligence guy." The site also says production is supposed to start in July (rather then the rumored June I guess). No more details then that. As a long time fan of his work, it should be interesting to see how he chews the scenery. Thanks to Wynton R. for the link.
