I just checked and apparently breach of contract is a crime. It might still be possible (if Tim knew exactly who the Antifa people behind this were) to have a TI suit, but you are technically correct. I'm was trying to apply what I saw on Racket's show here and that might not be wise.The grift is demanding $250k to fund what should be a fairly routine lawsuit. The value of the suit is probably around $25k, so he should be spending substantially less than that on legal fees. I don't know where he got the $250k figure from, but its fucking insane.
As for whether the theater is the "correct" target: of course it is. Tim and the theater entered into the contract. The theater breached the contract. The theater's breach cost Tim [X] amount of dollars in lost revenue and higher and additional costs. Tim is legally able to seek recovery of what the breach cost him. This is all routine business stuff.
As for the $250k number. I've never had to pay a lawyer before, so I didn't say anything about it. Now that I think about it, the numbers we saw with Meyer v Waid and Weeb Wars were really high, but they involved lawsuits against wealthy (and in the case of Weeb Wars multiple) defendants. If the theater was willing to accept Tim then they probably aren't very wealthy, so maybe it's fair to call bullshit on him asking for $250k.
