Conan the Barbarian, Arnold Schwarzenegger (1982)
Bodybuilding champion Arnold Schwarzenegger was able to effectively break into the movie industry through his role as Conan the Barbarian. Much of Schwarzenegger’s ultimately successful film career hinged on the fact that he looked unbelievably similar to the novel cover illustrations that depicted Conan in years past, causing the producers of the film to track him down and get him on board. The filmmakers were so dedicated to having him on that director John Milius constantly worked on his speech, having Schwarzenegger rehearse lines dozens of times before takes in attempts to take his Austrian accent down a couple notches.
Regardless of “acting,” Schwarzenegger put in the work to look the part of a leading conqueror, effectively fitting the needs of the role. Conan’s main motivation throughout the film is vengeance, so there’s of course, plenty of action and violence, without too many stops for prolonged dialogue.
