Did you watch The Carter? Did you even know it existed? Do you know who Dwayne Michael Carter, Jr. is? Have you ever heard of Lil' Wayne?
For me, the answer to all these questions except the last one is "No." And even with respect to the single "Yes," I couldn't provide you with many details. Rap star. That's the extent of my knowledge.
But if you answered "Yes" to more of those questions, or just like it when celebrities have appeals, then this is the case for you. It's an anti-SLAPP motion arising out of litigation between the dude who made the movie that documented Lil' Wayne's life, on the one hand, and Lil' Wayne on the other hand, who didn't much like the movie -- particularly various scenes that made him look bad in ways connected with the criminal charges against him.
