No amount of unverifiable "records" (just pieces of paper provided by somebody who has a multimillion dollar incentive to show one outcome) will change my mind.
But if they can produce the actual voice artist I'd be more open-minded.
Altman's outreach, his tweet, and the thousands of tweets and comments talking about how similar Sky is to ScarJo is enough to win the case in California.
They asked SJ, she said no. So they went to a voice actor and used her. Case closed, they didn't use SJ's voice without her permission. That doesn't violate any law to any reasonable person.
If there's one constant that can be relied upon, it's that "things that are reasonable to a lawyer" and "things that are reasonable to a normal human being" are essentially disjoint sets.
In litigation, any question whether X was "reasonable" is typically determined by a jury, not a judge [0].
[0] That is, unless the trial judge decides that there's no genuine issue of fact and that reasonable people [1] could reach only one possible conclusion; when that's the case, the judge will rule on the matter "as a matter of law." But that's a dicey proposition for a trial judge, because an appeals court would reverse and remand if the appellate judges decided that reasonable people could indeed reach different conclusions [1].
[1] Yeah, I know it's turtles all the way down, or maybe it's circular, or recursive.
