Aaron Eckhart talked to OnTheRedCarpet.com about drumming up some Marine brotherhood and letting his personalities 'out of the bag' one at a time at the "Battle Los Angeles" premiere on March 8, 2011.
"We went three weeks boot camp where we got to know each other, got to know our weapons in the middle of Louisiana in the summer time," Eckhart told OnTheRedCarpet.com. "So, it was really hot and sticky but it was great for the movie. Got to know each other really intimately, so you know, all that brotherhood's in the film."
In the movie, a Marine platoon is forced to defend Los Angeles after Earth is attacked by aliens. It's up to the Marine staff sergeant Michael Nantz (Aaron Eckhart) and his new crew to hold their ground against the unknown forces.
Eckhart hint that there was still a lot of the world to be saved after Los Angeles, leaving room for future installments.
"We saved LA, we have to go off and save the rest of world," Eckhart said. "You know, Tokyo and Paris and Rio and maybe a Carribean beach somewhere. So, we've got that in our future."
Eckhart recently worked with Johnny Depp on "The Rum Diary," which is based on a book by Hunter S. Thompson and is set for release sometime this fall. He also starred alongside Nicole Kidman in the Oscar-nominated film, "Rabbit Hole."
When asked how he keeps track of all the characters he signs on to play, Eckhart credited his multiple personalities.
"Well, I have many different personalities and I let one out of the bag at a time," the actor joked.
Eckhart is best known for his roles in "Thank You for Smoking," "Paycheck" and "The Dark Knight," where he played Harvey Dent who became the villain Two-Face.
"Battle: Los Angeles" was released on March 11, 2011. Watch a trailer below.
