1. Casablanca (1942)
Considered one of the great works of cinema of all time, the history of the filming of Casablanca is full of juicy anecdotes. Initially, its protagonists were to be Ronald Reagan and Ann Sheridan, but finally, the roles went to Humphrey Bogart and Ingrid Bergman. The director, Michael Curtiz, was making the necessary changes until he got the final casting. However, the script was never finalized, and modifications were made on the fly every day, which had the effect of making the actors nervous. The film won three Oscars: director, film, and screenplay.
2. The Godfather: Part II (1974)
Making a sequel to The Godfather was not an easy task, but Coppola achieved with this film a work that was as successful as the previous one. To shoot it, the director had a budget twice that of the original and, again, with a script by the novelist Mario Puzo. He won six Oscars: best-supporting actor (Robert de Niro), direction, film, adapted screenplay (Coppola and Puzo), artistic direction, and Music, by Nino Rota.
3. E.T. the Extra-Terrestrial (1982)
An alien is left stranded on Earth and is found by Elliot (Henry Thomas), a boy who hides him in his house, helped by his little sister (Drew Barrymore), and baptizes him E.T. The film meant the definitive consecration of Steven Spielberg within the film industry, and became the highest grossing in film history until Titanic, by James Cameron, managed to unseat him in 1997.
4. 2001: A Space Odyssey (1968)
Stanley Kubrick (The Shining) spent four years painstakingly preparing all the details for this film adaptation of an Arthur C. Clarke novel. It is considered the most important science fiction film of the seventh art. However, she only got one Oscar of the four for which she was nominated, the one for best special effects.
5. Schindler's List (1993)
Schindler's List (1993) is Steven Spielberg's most intense and personal work. Based on a true story, it received seven Oscars, including Best Picture, Best Adapted Screenplay, Best Editing, Best Director, Best Cinematography, and Best Art Direction. It starred Liam Neeson, Ben Kingsley, and Ralph Fiennes. Filming for the film took place in Krakow, Poland, over 72 days. A curiosity: in the 80s, Martin Scorsese had the opportunity to take this story to the movies, but finally Spielberg did it.
