With the release of Fantastic Beasts and Where To Find Them tomorrow. It is likely that if a success there will be more Harry Potter spin-offs here are some ideas.
Marauders Netflix Series
Through out the series, we have been given little bits of glimpses on the adventures of Harry’s father along with Remus Lupin, Sirius Black and Peter Pettigrew. We know that they created the Marauders Map and the mischief that followed. It would be great because it would bridge the gap between the end of the fifth Fantastic Beasts film to the 1st Harry Potter. It would also allow to go into a lot of detail something that Harry Potter never could do a lot of. It could also run at the same time as Fantastic Beasts for maximum Potter Experiences.
Quidditch Through The Ages
Fantastic Beasts originally started in a trio of spin-off books in The Hogwarts Library. It would be great to see a Potter spin-off play out like a sports film. The scenes from the past films have already been some of the best sequences in the films so to expand this out into a mighty ducks like underdog story following a team getting better eventually leading up to getting to the wold cup. This movie would be a perfect first stand alone film and would allow a lot of expansion and new opportunities.
Tales of Beadle The Bard Animated Series
This was the third book in The Hogwarts Library series and we have already seen one story from it executed brilliantly in Deathly Hallows Part 1 and arguably the best bit in the movie. To see the rest of the great book’s tales played out in the same art form would be fantastic. It could be made in either short film forms played before future films. Yet even better an Animated Series narrated by Emma Watson.
A more adult standalone film about the founders of Hogwarts it is know that they were driven to insanity and fought each other. It would be great seeing this unfold would be super cool.
We see Tom Riddle as a boy and we see Voldemort as a Murderer but what about in between what were the events that drove Tom to Voldemort what happened that pushed him over the edge and who was his first murder. This will provide a chance to provide some sympathy towards Lord Voldemort which would have felt out of place in the Harry Potter films.
Cursed Child Film
This one is a no-brainier but the recently written stage play should be a film no more said.
Ministry Of Magic
A Potter politics film could be really cool think house of cards but instead of old white men it’s old white wizard men. It is clear there are a lot of scandalism in the ministry and it would be super cool to explore.
Hogwarts Christmas Specials
A one off hour long special every year keeping up with current Hogwarts students and side characters current adventures.
