I hope it's not just a publicity stunt because it would really backfire.

A lot of these kinds of lawsuits are filed by people who will claim someone with a hit movie, t.v. show, book, or song somehow ripped off some obscure work by some obscure person. They have a tough time winning their cases because they often cannot prove the defendant had access to their ideas or their work.

But then you have cases like the one filed by the late Art Buchwald against Paramount, claiming it stole his script treatment and released it as "Coming To America" without crediting him or paying him. Buchwald won. You can read about it here:
