Task: Question Generation
Input (English): The most persistent theme throughout his films is tension in parent-child relationships. Parents (often fathers) are reluctant, absent or ignorant. Peter Banning in Hook starts off in the beginning of the film as a reluctant married-to-his-work parent who through the course of the film regains the respect of his children. The notable absence of Elliott's father in E.T., is the most famous example of this theme. In Indiana Jones and the Last Crusade, it is revealed that Indy has always had a very strained relationship with his father, who is a professor of medieval literature, as his father always seemed more interested in his work, specifically in his studies of the Holy Grail, than in his own son, although his father does not seem to realize or understand the negative effect that his aloof nature had on Indy (he even believes he was a good father in the sense that he taught his son "self reliance," which is not how Indy saw it). Even Oskar Schindler, from Schindler's List, is reluctant to have a child with his wife. Munich depicts Avner as a man away from his wife and newborn daughter. There are of course exceptions; Brody in Jaws is a committed family man, while John Anderton in Minority Report is a shattered man after the disappearance of his son. This theme is arguably the most autobiographical aspect of Spielberg's films, since Spielberg himself was affected by his parents' divorce as a child and by the absence of his father. Furthermore, to this theme, protagonists in his films often come from families with divorced parents, most notably E.T. the Extra-Terrestrial (protagonist Elliot's mother is divorced) and Catch Me If You Can (Frank Abagnale's mother and father split early on in the film). Little known also is Tim in Jurassic Park (early in the film, another secondary character mentions Tim and Lex's parents' divorce). The family often shown divided is often resolved in the ending as well. Following this theme of reluctant fathers and father figures, Tim looks to Dr. Alan Grant as a father figure. Initially, Dr. Grant is reluctant to return those paternal feelings to Tim. However, by the end of the film, he has changed, and the kids even fall asleep with their heads on his shoulders.
