Ne-Yo 'didn't understand Eckhart's method'

Ne-You has admitted that he struggled to comprehend his Battle: Los Angeles co-star Aaron Eckhart's dedication to method acting.

In an interview with Entertainment Tonight at the movie's LA premiere, the 'Because Of You' singer revealed that he became angry when Eckhart didn't acknowledge him during filming breaks.

"It was a little weird at first. I didn't understand the concept of staying in character the whole time," Ne-Yo said. "We almost got in a little tussle just behind me not understanding that he's still in character."

Despite initial on-set tension, the musician praised Eckhart for his dedication to the craft of acting.

He added: "He's a fantastic actor. I learned a lot just by watching him."

Battle: Los Angeles opens on March 11 in the US and the UK.
