Speculations subsided when Johnny Depp finally appeared as Gellert Grindelwald in the movie "Fantastic Beasts and Where to Find Them." This shows that succeeding film sequels, if any, will be themed on the grand conflict between the two main protagonists, the great wizard Albus Dumbledore and his nemesis, the evil Grindelwald.

According to Movie Web it cannot be denied that the central character in the movie is still Newt Scamander, a part splendidly played by Eddie Redmayne. The movie revolves around his adventures as a faulty upcoming wizard who wants only the best for wizardry.

Scamander is accused for being an unregistered wizard and is arrested by the association of wizards and loses the suitcase where he kept the different magical creatures he captured. The fantastic beasts that escape create mayhem and trigger the thrilling action scenes in the story.

The unlikely villain Credence Bareborne (played by Ezra Miller) was killed in the movie. But The Guardian speculates that he might be back very much alive  in the next "Fantastic Beasts and Where to Find Them" sequel or "Fantastic Beasts 2." 

If the reports are true, Credence will be joining partners Leta Lestrange (Zoe Kravitz) and Gellert Grindelwald in the next sequel. It was implied in the movie that Depp's Grindelwald is the source of Credence's powers so this connection might be developed into a subplot.

Leta Lestrange did not appear long in this movie but her connection with Grindelwald has caused Newt to cool off and distance himself from her. This could be another story angle that can be used by the film makers in the next sequel.

With a formidable threesome of evil Gellert Grindelwalg, Leta Lestrange and Credence Backbone on one side fighting against the great wizard Albus Dumbledore and his fellow good witches, the plot for "Fantastic Beasts and Where to Find Them" part 2 is ready to roll.
