In the end, the second Mario movie may be titled Super Mario Galaxy
, by Thibaut
Although early rumors pointed to it being called Super Mario World, Nintendo's next animated feature film will likely have a different name.
NBC Universal registered the domain name supermariogalaxy.movie on September 3. For the first film, the production company reserved the domain thesupermariobros.movie, and the final name was Super Mario Bros., the movie.
So, barring any last-minute changes, the second installment should be titled Super Mario Galaxy.
