Jaws

'Jaws' is arguably Spielberg's magnum opus.

The smash-hit movie created the concept of the modern summer blockbuster but the director did not have high expectations when the flick was released in 1975.

He recalled to W magazine: "I never would have guessed that so many people would have gone to see 'Jaws'. In my mind, the shark looked dumb. When I went to the first preview, in Dallas, and people were screaming and popcorn was flying at the screen, my first feeling was, 'Oh my god! I didn’t think any of this was going to work.'"

However, he does harbour some regret about how the film changed the public perception of sharks and led to the decline in the population of the sea creatures.
