6. Finn Is Lando Calrissian's Son
A movies merchandise can always give away crucial plot secrets, with the soundtrack release of The Phantom Menace which came out just before the movie casually mentioning Qui-Gon Jinns Funeral in the track listing. Studios are a bit more cautious about spoilers being leaked by merch now, but there appeared to be a
major slip-up when a toy for new character Finn revealed him to be the son of Lando. People have been trying to make the Lando connection with Finn from the beginning based entirely on skin colour but theres no concrete evidence to support that idea. Since the toy was listed by a private seller - and not by Disney or Lucasfilm who has no insider knowledge of the film or the story, its likely they just attached the name to get people talking about the listing. The item is also listed as a rare collectable, which seeing as there will be a hell of a lot of Finn toys made for Christmas, makes the accuracy of the description really dubious.
