ET is behind the scenes of the making of Transformers: Age of Extinction, introducing you to the film's new stars -- Jack Reynor, Nicola Peltz and Bingbing Li.
Nicola get her big break on the family Christmas movie, Deck the Halls, but don't let that fool you. She's one tough cookie!
"One of the great things about Nicola, is that she's not afraid to commit to anything," said co-star Jack Reynor. "Now whether that's the scene that she's doing, or whether it's committing to a performance or whether it's just committing to the physicality of the role, she's a tough girl."
She had to be to put up with her co-stars' shenanigans on set. Wednesdays on the set were declared Wild Weave Wednesdays, as Mark Wahlberg and Jack designated those days to rip out Nicola's weave in hazing the young actress.
Meanwhile, Jack had a thing or two to say about his working conditions.
"I had that one damn leather jacket every single day," said Jack. "The heat! Oh my God!"
Watch the movie to find out why newcomer Bingbing Li may have been a bigger deal than Mark on the set.
Transformers: Age of Extinction opens June 27.
