"Franco's pretty smart, but Franco's a child"
Arnold was owning everyone in that movie
The ownage was largely contrived, just like the T-shirt scene & Ferrigno shown working out in Brooklyn. Most of what Schwarzenegger said-about Franco, to Ferrigno, about his dad's funeral, etc. was BS for cinematic effect, to get attention. Very easily done-other than Waller the other BBs heard talking were stiffs, some of the least impressive guys possible. He wouldn't have been able to talk that way to Oliva, Mentzer or Szkalak who by no accident weren't interviewed or even shown. With Oliva out for political reasons he already knew he was going to win the show beforehand; talking trash in front of cameras to someone like Ferrigno with learning disabilities couldn't have been easier. The directors decided early on to make it a docudrama star vehicle focusing on Schwarzenegger rather than the documentary it was advertised to be.
The comment about Franco's back was made by Padilla-his only words. Another guy they should've shown but didn't.
