One might argue that this would be no different from some artist (or AI) painting a painting in the style of Picasso. As long as you make no attempt at passing it off as an original Picasso, it may be seen as ok, unless we extend intellectual property rights to cover style.... ... which we do already do, of course, if the protected item is something like an iPhone. In both cases, though, if you falsely claim that the actor/phone IS the real thing, then it's clearly forgery. And, I suppose, if you specifically bake too much of a similarity into it (ie a phone that looks exactly like an iphone, except the logo), one may argue that the likness effectively misleads the same way a forgery would, and that it can be illegal for that reason.
