This... is surprising. Both that Nintendo would want to greenlight a new Mario movie, as well as Sony Pictures making it. Obviously Sony Pictures is not Sony Computer Entertainment, and collaborations like this happen all the time in many industries, but most people will admit that it's an interesting development.
Apparently it will be an animated movie, and not a live action one (thankfully). I'm curious to see what will come of this. In any case it's in line with Nintendo's stated recent desire to branch their IPs off into other territories beyond games.
