The fourth installment in director Michael Bay’s sci-fi action franchise will open in cinemas on July 27 of this year (2014) and, as the brief clip reveals, will feature the introduction of the Dinobots: a popular group of characters from the Transformers comic books, TV series and toy line.

Transformers: Age Of Extinction will also introduce an entirely new cast including Mark Wahlberg, Kelsey Grammer, Stanley Tucci, TJ Miller, Sophia Myles and up-and-coming Irish actor Jack Reynor. Speaking previously about the film, Wahlberg said the latest installment would be “very different” from the previous films in the franchise.

The three previous Transformers movies starring Shia LaBeouf, who declined to return this time out, grossed over $2.67 billion (£1.7 billion) collectively at the box office worldwide.
