Ford was a struggling actor when he was cast in Spielberg's 1977 film "Star Wars." The film was a huge success, and Ford became a star overnight. He went on to star in several other successful films, including "Raiders of the Lost Ark" and "Indiana Jones and the Temple of Doom."
Hanks was also an unknown actor when he was cast in Spielberg's 1988 film "Saving Private Ryan." The film was a critical and commercial success, and Hanks won an Academy Award for Best Actor. He went on to star in several other successful films, including "Forrest Gump" and "Cast Away."
DiCaprio was a teenager when he was cast in Spielberg's 1997 film "Titanic." The film was a massive box office success, and DiCaprio became a global superstar. He went on to star in several other successful films, including "The Departed" and "The Wolf of Wall Street."
Spielberg's gamble of casting relatively unknown actors in some of his biggest films has paid off handsomely. These actors have gone on to become some of the biggest stars in Hollywood, and they have all starred in some of the most successful films of all time.
In addition to Ford, Hanks, and DiCaprio, Spielberg has also cast other unknown actors in his films who have gone on to become stars. These include Michelle Pfeiffer, Robin Williams, and Kate Winslet.
Spielberg's willingness to take risks with casting has helped to make him one of the most successful directors in Hollywood. He has a keen eye for talent, and he is not afraid to give unknown actors a chance to shine. This has paid off handsomely for him, and it has helped to make some of his films into classics.
