Here's what we know:
* A "Finding Nemo: The Musical" already exists. It premiered at Disney's Animal Kingdom in 2007 and is still running.
* Broadway productions are expensive and risky. It's not guaranteed that a popular movie like Finding Nemo would translate successfully into a Broadway musical.
* Disney is actively developing other Broadway productions. They have a strong track record with successful musicals like "The Lion King," "Aladdin," and "Frozen," which could potentially take priority over a Finding Nemo musical.
While a Finding Nemo Broadway musical is not impossible, it is not currently in development. It's best to keep an eye on Disney and Broadway news for any potential announcements in the future.
