We get details on Harold Attinger in Transformers 4, set to be a villain of sorts in the movie, by the actor playing the character, Kelsey Grammar.
Kelsey Grammar offers a short description about Attinger to Empire.
"Malevolent" is the word Grammer uses to describe his big bad, Harold Attinger. "He’s a no-nonsense guy," he told Empire. "He’s lived his life in the shadows for 30 years in the service of his country, and he likes to be unremarkable yet very efficient."
While no plot details have been officially released from Paramount, we can speculate the reason for Kelsey Grammar being a villain is that he butts heads with the Transformers (possibly both the Autobots and Decepticons) as he may have taken their tech to build and design the Dinobots. However that is just a guess based on what is said to have been a redacted synopsis stating powerful businessmen take the Transformers tech as their own. Regarding the Dinobots, a producer on the film recently confirmed at least one will be featured as well as the fact the official title hints at dinosaurs with "Transformers: Age Of Extinction."
It also seems as if Unicron may be thrown into the mix as a leaked call sheet named Cyclonus. Any chance Kelsey Grammar's character is connected?
Transformers 4 has a Summer 2014 release directed by Michael Bay and starring Mark Wahlberg, Jack Reynor, Nicola Peltz, Sophia Myles, Li Bingbing, T.J. Miller and Kelsey Grammar.
