Q:I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Parenthood Movie plot: Gil Buckman (Steve Martin) is an anxious sales executive in the St. Louis area. When he finds out that his eldest son, Kevin (Jasen Fisher), has emotional problems and needs therapy, and that his other two children, Taylor (Alisan Porter) and Justin, may have issues as well, he begins to blame himself and questions his abilities as a father. When Gil's wife, Karen (Mary Steenburgen), announces she is pregnant with their fourth child on the same day he quit his sales job, he is unsure whether he can cope. Gil is also concerned and convinced that the financial burdens of another child and office politics at work are turning him into the distant workaholic he hated his own father, Frank (Jason Robards), for being. Stressed by family and work issues, he opens up to Frank about his doubts as a parent. Frank tells him that he worries too much, and they have a reconciliation of sorts with Frank telling Gil, that fear and apprehension for one's children never ends. When a hired cowboy character fails to show up at Kevin's birthday party, Gil dresses up as a cowboy himself and hilariously understudies the role. Gil's sister, Helen (Dianne Wiest), is a divorced bank manager whose dentist ex-husband wants nothing to do with their kids, Garry (Joaquin Phoenix) and Julie (Martha Plimpton). Garry, who has just entered puberty, is shy, friendless, and likes to be alone in his room with a mysterious paper bag. At first Helen worries that it contains drugs or alcohol, but it actually contains porn videos and Playboy magazines. Julie is still in high school. In spite of her high SAT scores, she is not interested in her education. She and her slacker boyfriend, Tod Higgins (Keanu Reeves), get married, ultimately resulting in her becoming pregnant and him moving into Helen's house. When Helen asks Tod to talk with Garry, he is able to reassure Garry that his obsession with girls and sex is normal for a boy his age, something that is a relief to Garry. This also increases Helen's respect for Tod. Eventually she supports his and... My question: What is Helen's children's name?
A:
Helen's children are Garry and Julie.
