Conan the Barbarian (1982)
However, mihailo.razvigor says that Conan the Barbarian is actually quite deep. It explores many themes such as futility of revenge, the power of persuasion, the importance of inner strength, as well as free will, honor, friendship, freedom, and more. It also has a surprisingly poignant performance by Schwarzenegger, as well as an amazing score by Basil Poledouris.
