The 43-year-old "Hobbit" star revealed that the character he plays in very "ambiguous" and is neither a hero nor a villain, reported Aceshowbiz.
"He works for the American government. He works in conjunction with the superheroes, and certain agencies that help to tame the superheroes' power, I suppose. So you're not quite sure which side he's on. It looks a little bit like he's playing one game when actually he's playing another," Freeman revealed.
"It's the kind of character I like because it's ambiguous and because you don't know whether he's good or bad. I like that area that isn't black or white, I like the greys, because I think there's just more fun to be had in not playing one obvious line," he said.
The film is scheduled to release on May 6, 2016.
