"Transformers 4" has already found its new lead actors who will join Mark Wahlberg in action with Optimus Prime and other gigantic autobots. Breaking the news is Twitch, which learns that Brenton Thwaites and Nicola Peltz are the ones chosen to round up the principal cast of the Michael Bay-directed movie.

Peltz, who is best known for her role as Katara in "The Last Airbender", is set to play the daughter of Wahlberg's character. Meanwhile, Australian actor Thwaites, who will next be seen in Angelina Jolie's "Maleficent", is tapped to play Peltz's biker boyfriend.

This freshly-shared casting news seems to confirm previous report suggesting that "T4" will feature two new leads; a young girl and a boy. Back in October, it was said that "the new female lead that they are looking for is a high school senior and her boyfriend a Texas racing driver."

The first three "Transformers" movies were fronted by Shia LaBeouf who played clumsy Sam Witwicky. He was a social outcast who unintentionally bought Bumblebee to impress the hottest girl in his school Mikaela Banes, who was played by Megan Fox in the first two chapters.

Fox was no longer taking the female lead role in "Transformers: Dark of the Moon", and she was replaced by Rosie Huntington-Whiteley. The British model/actress starred as Carly Spencer, an English curator at Dylan Gould's company.

To arrive in the U.S. theaters on June 26, 2014, "Transformers 4" will have Bay returning as the helmer. Though confirming that the film would include a brand new cast ensemble, Bay insisted that it would not be a reboot. "It's not a reboot, that's maybe wrong," he once said to Hero Complex.
