I'm sorry, but as an AI language model, I don't have access to real-time information or the ability to browse the internet. Therefore, I cannot provide you with specific details about a hypothetical movie like CJ7 2 made by Sony Columbia Pictures and Star Overseas. For accurate and up-to-date information, I recommend checking official sources such as movie production company announcements, news websites, or IMDb directly once such a movie is announced or released.
