Themes-

Spielberg's films often deal with several recurring themes. Most of his films deal with ordinary characters searching for or coming in contact with extraordinary beings or finding themselves in extraordinary circumstances. In an AFI interview in August 2000 Spielberg commented on his interest in the possibility of extra terrestrial life and how it has influenced some of his films. Spielberg described himself as feeling like an alien during childhood, and his interest came from his father, a science fiction fan, and his opinion that aliens would not travel light years for conquest, but instead curiosity and sharing of knowledge.

A strong consistent theme in his family-friendly work is a childlike, even naïve, sense of wonder and faith, as attested by works such as Close Encounters of the Third Kind, E.T. the Extra Terrestrial, Hook, and A.I. Artificial Intelligence. According to Warren Buckland, these themes are portrayed through the use of low height camera tracking shots, which have become one of Spielberg's directing trademarks. In the cases when his films include children (, E.T. the Extra Terrestrial, Empire of the Sun, Jurassic Park, etc.), this type of shot is more apparent, but it is also used in films like Munich, Saving Private Ryan, The Terminal, Minority report , and Amistad. If one views each of his films, one will see this shot utilized by the director, notably the water scenes in Jaws are filmed from the low-angle perspective of someone swimming. Another child oriented theme in Spielberg's films is that of loss of innocence and coming-of-age. In Empire of the Sun, Jim, a well-groomed and spoiled English youth, loses his innocence as he suffers through World War II China. Similarly, in Catch Me If You Can Frank naively and foolishly believes that he can reclaim his shattered family if he accumulates enough money to support them.

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 his 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. Most of his films are generally optimistic in nature. Critics frequently accuse his films of being  overly sentimental, though Spielberg feels it's fine as long as it is disguised. The influence comes from directors Frank CApra and John Ford .

Contemporaries –

In terms of casting and production itself, Spielberg has a known penchant for working with actors and production members from his previous films. For instance he has cast Richard Dreyfuss in several films: Jaws, Close Encounters of the Third Kind, and Always. Aside from his role as Indiana Jones, Spielberg also cast Harrison Ford as a headteacher in E.T. the Extra-Terrestrial (though the scene was ultimately cut). Although Spielberg directed him only once (in Raiders of the Lost Ark, for which he voiced many of the animals), veteran voice actor Frank Welker has lent his voice in a number of productions Spielberg has executively produced from Gremlins to its sequel Gremlins 2: The New Batch, as well as The Land Before Time (and lending his voice to its sequels which Spielberg had no involvement in), Who Framed Roger Rabbit, and television shows such as Tiny Toons, Animaniacs, and SeaQuest DSV. Recently Spielberg has used the actor Tom Hanks on several occasions and has cast him in Saving Private Ryan, Catch Me If You Can, and The Terminal. Spielberg also has collaborated with Tom Cruise twice on Minority Report and War of the Worlds. Spielberg has also cast Shia LaBeouf in four films: Transformers, Eale Eye, Indiana Jones and the Kingdom of the Crystal Skull, and Transformers: Revenge of the Fallen. Spielberg prefers working with production members with whom he has developed an existing working relationship. An example of this is his production relationship with Kathleen Kennedy who has served as producer on all his major films from E.T. the Extra-Terrestrial to the recent Munich. Other working relationships include Allen Daviau, a childhood friend and cinematographer who shot the early Spielberg film Amblin’ and most of his films up to Empire of the Sun; Janusz Kamiński who has shot every Spielberg film since Schindler’s List and the film editor Michael Kahn who has edited every single film directed by Spielberg from Close Encounters to Munich (except E.T. the Extra-Terrestrial). Most of the DVDs of Spielberg's films have documentaries by Laurent Bouzereau.

A famous example of Spielberg working with the same professionals is his long time collaboration with John Williams and the use of his musical scores in all of his films since The Sugarland Express (except The Color Purple and Twilight Zone : The Movie). One of Spielberg's trademarks is his use of music by John Williams to add to the visual impact of his scenes and to try and create a lasting picture and sound of the film in the memories of the film audience. These visual scenes often uses images of the sun (e.g. Empire of the Sun, Saving Private Ryan, the final scene of Jurassic Park, and the end credits of Indiana Jones and the Last Crusade (where they ride into the sunset)), of which the last two feature a Williams score at that end scene. Spielberg is a contemporary of filmmakers George Lucas, Francis Ford Coppola, Martin Scorsese, John Milius, and Brian De Palma, collectively known as the "Movie Brats." Aside from his principal role as a director, Spielberg has acted as a producer for a considerable number of films, including early hits for Joe Dante and Robert Zemeckis.
