According to the folks at ArsTechnica, this was evidenced in the emails sent back and forth between Sony Pictures’ then-co-chair Amy Pascal and producer Avi Arad. The email talked about a “full court press” with regards to an animated version of Super Smash Bros, and also mentioned Arad “planning to meet with his Nintendo guy (who he has been courting for a couple of years) when he goes to Japan.”
If this sounds familiar it is because last year we reported on the leak as well, but what’s interesting is that apart from the plan to make a Super Smash Bros animated series, the emails also revealed that Arad and Pascal were also trying to lock down the film right to other Nintendo franchises, such as Mario, Zelda, Donkey Kong, and etc.
Arad was quoted as saying about his trip to Japan, “I am going to try and bring back a little plumber. I guess we can all use our pipes cleaned.” He also asked if Pascal might be interested in Pokemon because that “the other property I am working on with Nintendo.” It is unclear if Arad was successful in gaining the film rights for Sony Pictures, or if and when such movies/TV series would be released, but it would be interesting to keep an eye out for.
