No Arnold had a plan for Arnold..he's an utter prick
Who the fuck else is he supposed to have a plan for? Zane? Lou? Robby?
So none of these other guys were out making any kind of connections or had any notion or plan of making a movie about bodybuilding. But Arnold did. He gets to know Butler and Gaines and works with them to make the project for the pumping iron movie. Does he not deserve the spotlight, especially given that he was by far the best bodybuilder of the era. It was pretty obvious he was going to win again.
So what was Arnold supposed to do, convince butler and Gaines to spend their time building the movie around Zane? A guy who showed up to the show in probably his worst shape- by his own words.
No. Arnold made these things happen. No one else did. He was the champion he rightfully was in the spotlight.
