Uh… well first of all, I don’t see what any of those things have to do with each other. To put my objections in some kind of order:
The idea that actors’ skill at lying is a reason to distrust their testimony is ridiculous. Juries, and people in general, are much worse lie detectors than they believe themselves to be. The bar is set so low that probably only really, unusually bad liars are ever caught by that method.
That said, experience and skill at acting probably does generalize into skill at other forms of lying—that seems intuitively true, and it’s certainly been the case in my experience, so I have no reason to doubt it.
The unrelated claim of whether actors are equally likely to be dishonest as anyone else is also a terrible indicator of their reliability under oath. Presumably people who perjure themselves have a compelling reason, such that a constitutional tendency toward honesty wouldn’t do what the threat of jailtime did not.
That said, I have no idea whether actors are more, equally or less likely to be dishonest than the general population. I’m not sure how you’d go about testing that hypothesis, either.

Does that about clear it up?
