Transformers: Age of Extinction is a 2014 American science fiction action film based on the Transformers toy line. It is the fourth installment of the live-action Transformers film series and the sequel to Dark of the Moon (2011), taking place five years after its events. Like its predecessors, it was directed by Michael Bay and written by Ehren Kruger, with Steven Spielberg and Bay as executive producers. It stars Mark Wahlberg, Stanley Tucci, Kelsey Grammer, Nicola Peltz, Jack Reynor, Sophia Myles, Bingbing Li, Titus Welliver, and T. J. Miller. It does not feature the original human cast from the previous three films, and instead introduces a new human cast and many new Transformers, including the Dinobots. Returning Transformers include Optimus Prime, Bumblebee, Ratchet, Brains, and Megatron. The screenplay was written by Ehren Kruger. Age of Extinction was the first feature film to be shot on smaller digital IMAX cameras, as well as various other film formats, such as IMAX 70mm film cameras, digital stereo 3-D, and anamorphic and spherical 35mm film.
