The 41-year-old actress insists her 'Allied' co-star - who was recently told her won't face charges over a row with his 15-year-old son Maddox on board a private jet - is a "good man" and enjoyed working with him on the World War II movie because he was so committed to the project.

She said: "[Brad is] an amazing partner who is such an amazing actor.

"I was very impressed by his determination and commitment, and he's such a good man, besides being an amazing actor. He's proved it many times."

Marion - who was forced to deny reports she and Brad had had an affair following his split from wife Angelina Jolie in September - has had to change the way she works in recent years because her five-year-old son Marcel "freaks out" if she takes her characters home with her so she now has to make a very clear divide between her personal and professional lives.

The French beauty - who is expecting her second child with partner Guillaume Canet - said: "Having a child changes things because I have to organise myself differently.

"I have to separate my life as a woman from my life as an actress.

"Usually when I work, I'm totally dedicated to the role and when I leave the set I take some of the character home with me, but I can't take anyone home with me now because my son would freak out.

"He hates coming on set because he feels there's something totally different. My hair is different, my look is different, but more than that my energy is totally different."

While the 'Nine' star adores her work, she is planning to scale back her commitments when her second child is born.

She told the Daily Telegraph newspaper: "I love being an actress but I might work less, certainly less than last year when I worked a lot."
