EXCLUSIVE: Meet Isabela Moner, the Scene-Stealing Breakout Star of 'Transformers: The Last Knight'

By
Isabela Moner just might be a household name afterTransformers: The Last Knight hits theaters.
The 15-year-old actress holds her own against the evil robots in the action movie, as ET's Cameron Mathison found out when he visited the set.
In the fifth Transformers film, we catch up with Mark Wahlberg's character, Cade Yeager, a couple years after the big battle in Chicago. Now a man on the run, Yeager finds himself being dragged to England, where he meets up with new characters played by Laura Haddock and Moner.
Moner admits that she was initially intimidated by Wahlberg.
"I couldn't tell if he liked me or not, becuase he's low key," Moner told Mathison. "Later on throughout the movie, we got to be friends. We're friends. We're cool."
Despite the age difference (Wahlberg is 40 years her senior), Moner knew she would have to be in top physical condition to match Wahlberg's energy while filming action sequences.
"I worked out before to have the stamina to keep up with Mark Wahlberg when we run through obstacles," Moner said.
"He's committed," Moner added of Wahlberg's 3:30 a.m. workouts. "I wake up like 10 minute before call time. I'm not going to lie."
