In 1968, he said after 2001 that "the science fiction movie we've all been waiting for still hasn't come along", and that Things to Come was the most recent serious large-budget film with good actors and a science fiction screenwriter. However, in the second half of the 1960s a number of exceptional films appeared, transforming science fiction cinema. 1966 saw two significant films released: first Fahrenheit 451 was a social commentary on freedom of speech and government restrictions and then Fantastic Voyage where the science fiction film "boldly went where no man had gone before" when Raquel Welch ventured inside a human body. Finally in 1968 the extremely camp Barbarella paid homage to the sillier side of earlier science fiction. In the late 1960s, the Indian director Satyajit Ray planned on making The Alien, a story about a boy in Bengal befriending an alien. Production of the film was cancelled, but the script was released and available throughout the world. Ray believed that the 1982 Steven Spielberg film E.T. the Extra-Terrestrial was based on The Alien, though Spielberg states that it was not. Planet of the Apes (1968) was extremely popular, spawning four sequels and a television series. While not strictly-speaking science fiction, some of the James Bond films included a variety of science fiction-like gadgetry. Possibly the most significant Science Fiction film of the 1960s was 2001: A Space Odyssey of 1968, directed by Stanley Kubrick and written by Kubrick and Arthur C. Clarke. 2001 is regarded as the seminal entry in the science-fiction genre as it influenced several later entries. Steven Spielberg, one of the genre's most well-known figures aptly called 2001, 'the big bang of science-fiction.' This movie was groundbreaking in the quality of its visual effects, in its realistic portrayal of space travel, and in the epic and transcendent scope of its story. Science fiction movies that followed this film would enjoy increasingly larger budgets and ever improving special effects. Clarke has told of screening earlier science-fiction films for Kubrick, and Kubrick pronouncing them all awful, without exception, even Things to Come. 2001 was the first science fiction art film and had a philosophical scope that earlier films had not attempted. Many critics called it an incomprehensible mess when it first appeared. Today, it is widely lauded by critics as one of the greatest films of all time.
