Disney decides to remake the three Star Wars prequels because they're terrible and thinking up a new movie series is hard. The expectation is that Disney will eventually remake all $9$ films, but that will take decades to complete. Disney casts Johnny, a ten$-$year$-$old boy, to play Anakin Skywalker$/$Darth Vader. Disney and Johnny execute a lifetime services contract to act in the first three movies, and if they are made, the final six. The first three movies are made and are wildly successful. On Johnny's $18$th birthday, Disney calls Johnny and his agent to notify them they are going to make the final six movies. Which of the following is FALSE?

Johnny could ratify the contract and be bound to the contract as an adult.

Johnny could try to negotiate a new contract if Disney is willing to do so$.$

Johnny must act in the final six movies because he benefited from the first three.

Johnny could disaffirm the contract because he was a minor when he signed it$.$
