Perhaps many viewers will agree that Terminator (at least the first two parts) is the main action movie in the history of cinema. The role of T-800 made Arnold Schwarzenegger a world-famous actor and one of the most respected people in Hollywood.
The legendary franchise was imitated, films about the stern humanoid robot were repeatedly parodied. In general, the cultural influence of James Cameron's creation was colossal. However, few people know that Cameron did not come up with the famous plot alone.
Yes, his friend William Wisher Jr. worked on the script together with the director, but that's not the point. Soon after the film was released, Cameron was sued.

The defendant, science fiction writer Harlan Ellison, accused the director of plagiarism. Back in 1957, Ellison wrote the story 'Soldier'. According to the plot, two infantrymen from the 3042nd are transported to 1964 to save the earth. Another work by the writer, 'The Demon with the Glass Hand', in which time travelers protect the savior of humanity, also came under fire. However, the case never reached the hearings, because the matter was resolved amicably. The offended writer was paid 65 thousand dollars, and he agreed to settle the matter peacefully. James Cameron never admitted his guilt.
