Back in May, Nintendo announced that they were looking to do theatrical animated films based on a variety of their IP.
This came as a shock exciting many, as Nintendo was known for being very protective of their properties since most early productions received poor responses.
While many are excited to learn which series Nintendo will be adapting, we may have the answer to who will be producing at least one of them. A podcast released on Nickelodeon's YouTube channel has been outed to be allegedly detailing a purported Nintendo property.
Here's a transcription:
We have a project now that we're doing that needs to go unnamed, based on one of the most world famous video games of the last 30 years, that we've had in our shop for twelve years without being able to get it started. But there were great characters and a great story, and eventually we got it going.
The person stating this is Fred Seibert of Frederation Studios animation, his production studio is famous for working on Adventure Time and Fairly Oddparents.
It seems as if he's had a lot of interest and excitement over producing this feature, so it almost goes without saying that it only recently allowed him to get started creating it with his team. The aforementioned announcement of Nintendo finally opening up to animated films, seems to support this thought-process.
Fred's line stating that the title had been, "in our shop for twelve years" unfortunately means that the title will not be Splatoon related. On that note what Nintendo series would you want to be adapted into a feature film? This particular writer would choose Balloon Fight any day of the week.
As for now, all we can do is wait since there's been no confirmation from Nintendo.
