The Business Insider has revealed new photos of the Dinobots, including Grimlock, Scorn, Slug and Slash via the Hasbro toy line from the 2014 Toy Fair. The toys were made up of metal and plastic, designed intricately to look striking and quite like a mean machine with massive claws, silver steel jaw and orange and black body. The dinobots are robots that become dinosaurs.

The movie's package artist posted a hint on Twitter: "I saw the concepts of the Dinobots. Guys who like dinosaurs will freak out with Transformers 4," he tweeted in Portuguese.

When the film finished shooting in Hong Kong, where 30 minutes of the movie was held, Director Michael Bay said he filmed a crucial shot of the movie at the Wulong Karst National Geology Park. This was where a group of Transformers will meet another Transformers team to battle their way out of crashed starship crater. It was speculated that the other team of Transformers was actually the Dinobots.

When Wahlberg was asked about the Dinobots in the 2014 film, he said: "Oh, I cannot talk about that. It is on a lot of people's bucket list but I have not seen them." Meanwhile, Jack Reynor is the male lead to play a race car driver in the film. Nicola Peltz will be Reynor's girlfriend, while Wahlberg will play Flynn Vincent, Peltz's father, whose alter ego is Cade Yaeger. Harold Attinger, the main antagonist, a counter-intelligence agent in the film, will be played by Kelsey Grammer.

"I think the emotional core, the human element is gonna be extremely powerful," Wahlberg said. "It is an ordinary man doing extraordinary things to save and keep his daughter alive - and her boyfriend he did not know anything about."
