The 51-year-old American actor, in an interview to V Magazine, opened up about what it was like working closely with Jolie while shooting the movie.
"It's surprising how much I enjoy the direction of my wife. She's decisive, incredibly intuitive, knife-sharp, and might I say, sexy at her post," Pitt told 'V Magazine'.
The film follows the emotional fallout of a married couple, played by Pitt and Jolie.
"It was probably not the wisest way to spend a honeymoon. But then again, fighting to make something together... What better metaphor for marriage?" said the actor, who stars opposite Jolie, 40.
The film will hit theatres on November 13.
