They reached out to her a couple days before they launched, and said hey do you want to maybe reconsider that thing where we asked you about this a couple times, and both times you told us to go fuck ourselves
And then they told the media that they were in discussions with her, when the discussions were her lawyer telling them to go fuck themselves
And then Altman tweeted "her"
And then when it launched, it was according to her so freakishly similar that her friends were weirded out by it
If it was some different actress saying hey this sounds a lot like me, that wasn't the one that they clearly had in mind when they were making their plans about it, then I could see a pretty strong argument to say hey relax buddy sometimes different people just sound similar
I don't really know and I don't care enough to listen to samples for myself and see what I think. But just based on the above set of random facts I feel like probably she has a fairly strong case.
