Not really relevant to Arnie, but Ghostbusters was basically the brainchild of Dan Aykroyd and Harold Ramis. Ramis probably brought Reitman on board because they had worked together a number of times (they were both fresh off of Stripes, which incidentally co-starred Murray).

Actually it's kind of shocking how many of the biggest names in both action and comedy that decade overlapped. As for Arnie's actual acting ability, I'll put it this way: there's probably a reason Dwayne Johnson is virtually the only actor with a similar kind of background who has had anywhere near as much success. A lot of it is that Arnie kept finding roles that suited him, but many of said roles were also very different from each other. Like I said though I did enjoy him sort of playing with his tough guy image in Twins and Kindergarten Cop, so YMMV.
