The actress and wife of John Travolta, who lost her 16-year-old son in January, returned to the set of her new film Casio Jack, and believes that work helps her to deal with the grief, reports FemaleFirst.
Director George Hickenlooper said, "She wanted to do this to get back to work. She talked to me about her loss. She is deeply affected by it and brought that to her character."
Preston and Travolta, who also have a daughter, Ella Bleu, 8, are still mourning their son, Jett.
