Ok, so Terminator gets a "pass," but what about Last Action Hero? Jingle All The Way? Twins? Predator? In no film wherein he's written as American (ostensibly by birth or by right) is he ever acknowledged to be an immigrant. Not saying it's a problem, just odd that no one ever wrote a script [that I'm aware of] that addresses his not-native status when his accent is about as iconic as his visage.
Because the simple fact is that Arnold is not an ACTOR. He's an entertainer. His acting skills are horrible, and almost non-existent. He isn't hired because of his emotional range and his ability to act his heart out, in a way that will leave the audiences weeping for generations. He is hired because he's a steroided out meatslab, that makes women (and some dudes too) get wet, and dudes wish they were him getting the women wet. He looks good when they slather him, shirtless, in oil, and give him a big penis, sorry gun, to point at people, while pyrotechnics go off in the background. He has a baseline charisma to him, that is like the epoxy glue of his personality, that helps carry his sub-par acting to massive monetary success.
Not saying he's a bad person, but he's not an actor, and much less a GOOD actor. There is a cost assessment that has to be considered, on whether anyone wants to spend part of their budget, to TRY (and likely fail) to get Arnold to voice lessons, to learn how to suppress his accent, much less adopt OTHER accents believably, or just say "fuck it, nobody cares that he always sounds Austrian, they're here to watch him shoot things and say one-liners."
And you can tell this, by pretty much all of his really good, successful films, that actually have him talking instead of shooting things, he gets paired up with someone with actual acting skills, who basically carry all the scenes. The heavy lifting of the acting, and Arnold just usually responds to things. In short sentences, that are fairly simplistic in nature. He's the straight man in the buddy pairing equation. I mean fuck, in Kindergarten Cop, that task is carried by a GROUP OF CHILDREN! Danny Devito did it in Twins, Edward Furlong did it, along with Linda Hamilton in T2, Carl Weathers in Predator, the kid in Last Action Hero (which I think is a criminally underrated film btw). Jamie Lee Curtis, and Tom Arnold in True Lies. The list goes on and on. THEY do the actual acting, saying the big, complicated sentences, emoting like a human, etc. Arnold just usually stands there and looks....I dunno...beefy and confused I guess.
Which, again, is FINE. I don't have a problem with him, but I don't consider him anything close to being an actor, and apparently he thinks so too.
