Weider's the star of the show there. That's a guy that's been through it all before, and knows how to get shit done. You can tell he probably thought some of that stuff was small potatoes, but he lets Arnold have his moment, and by extension, gains more favor with him.
It's eat or get eaten.
Arnold always made sure he got the best meal, and got it first.
Can't blame him for that, it is how you get results.
The guy is wildly succesfull, and he deserves it.
No bodybuilder before or after him has or will ever achieve what Arnold has achieved.
Pretty much this and this.
I guess Getbiggers don't like success?
Also, the pumping iron film crew shot hundreds and hundreds of hours of footage. The only 'scripted part' was Waller, Robby and Denny Gable throwing the football.
Everything else was created through editing the footage. They weren't acting. FFS, you've seen Arnolds movies, he can't act for shit.
Other people have said Arnold fought all the time in his youth. Drinking at bier gardens in Austria. Don't know how well he fought but Mentzers greatest fighting moment is walking towards Arnold and pointing a finger before Ben Weider held him back... imagine being "held back" by Ben Weider. LOL, sounded.... intense. LOL.
