It's interesting to hear Arnold's REAL voice back at that time on the DVD version. Some scenes you're like, "Huh? What did he just say?"
Arnold "Strong" couldnt speak English when they filmed that..
When they went for casting interviews Joe Weider went along with Arnold and done all the talking , he said Arnolds a great shakesperian actor and he musnt talk as he is resting his amazing voice..they beleived him , Arnold got the part and the rest is history
