Actress Angelina Jolie, in Tokyo for the weekend opening of action thriller “Salt,” brushed off rumors about her shaky relations with Brad Pitt. “He was just a wonderful father,” she said Tuesday of Pitt, during work on the film, in which she plays a tough spy. He often brought the children to the set, she recalled. Pitt and Jolie have been partners since they began a relationship while working on the 2005 film “Mr. and Mrs. Smith.” They are raising six children. Asked about her ability to work and maintain a happy family, Jolie told reporters at a Tokyo hotel: “Brad is the word that makes it possible.” Jolie, who arrived Monday, brought four of the children along on the Japan trip. They have already spent some time shopping for toys inspired by Japanese director Hayao Miyazaki's animation characters Ponyo and Totoro, she said. Jolie, 35, acknowledged she once surprised her 8-year-old son Maddox with her disguise as a male naval officer in “Salt.” He came into the room and reluctantly shook hands with the person he didn't know was his mother. “I play these roles, but I'm always in every minute their mom first,” she said. “I'm a bit of a goofy. I'm funny at home, I think.”
