Rehevkor has a point precedent seems to be in favor of keeping the title unchanged For some reason or another when a sequel is released the original keeps the film title Whether not this is the best way is debatable but I don t want to get into that now To be perfectly honest I don t feel particularly compelled in either direction right now There are good reasons on both sides and neither would have any significant effect on how easily the article would be found I suppose if no one is aware that there was a first film before I Want to Believe they might mistakenly think this article describes it so in that case I d go with 1998 film Again I am definitely against Fight the Future though That wouldn t be helpful except to fans who are used to hearing that tagline Simply creating redirects for all these titles might be the best option here
