Newt Scamander carries a wand, practices magic, and works for the Ministry of Magic even though he was expelled from Hogwarts, which puzzled several fans online especially since Hagrid wasn't afforded those liberties. J.K. Rowling explained that the reason for this will be revealed throughout the series.

Zoƫ Kravitz's character, Leta Lestrange, is expected to have a much larger part in this film. The Lestrange family has a very notable reputation in the wizarding world, where the series previously featured Bellatrix Lestrange (played by Helena Bonham Carter), who married into the family, and to a lesser extent, her husband Rodolphus and his brother Rabastan. They are one of the original Sacred Twenty-Eight (truly pureblood families) and are known for their extreme wealth, pureblood supremacy, and practice of the Dark Arts. A few members of the family even become Death Eaters.

Filming began in January 2017. On Twitter, J.K. Rowling announced that Alison Sudol would return, alongside the already confirmed Eddie Redmayne and Katherine Waterston.

J.K. Rowling has confirmed on Twitter that Newt Scamander will be the main character in the following movies.

J.K. Rowling has confirmed that Newt Scamander will be the main character in the next movie, even though David Heyman said otherwise.

Although Theseus is the older brother of Newt, Eddie Redmayne, who played Newt, is 8 years older than Callum Turner who portrayed his brother Theseus in the film.

Principal filming was completed on December 20, 2017.

Jude Law previously appeared in Sky Captain and the World of Tomorrow with previous Dumbledore Michael Gambon. He also appeared in Road to Perdition with Ciaran Hinds, who played his brother Aberforth. In Sherlock Holmes: A Game of Shadows he works with Jared Harris, son of previous Dumbledore Richard Harris. And in The Imaginarium of Doctor Parnassus, he worked with Johnny Depp and Colin Farrell.

J.K. Rowling has confirmed that the story arc of the series will span 19 years, leading up to the epic battle of Albus Dumbledore and Gellert Grindelwald in 1945.

According to the screenplay of Fantastic Beasts and Where to Find Them (2016), Leta Lestrange had an experiment she was conducting at Hogwarts that went wrong, and it endangered the life of a student. Newt Scamander took the blame, and it's rumored that's why he was expelled from the school.

Johnny Depp signed on without reading a script. He wanted to be a part of the series because he is a self-proclaimed massive fan of the series.

Scamander took the blame for the experiment and the other professors threatened to expel him from Hogwarts but Dumbledore stood up for him, so he was never expelled, he is listed as a graduate.

According to Ezra Miller, Dumbledore will feature in this installment.

Nicolas Flamel (maker of the Philosopher's Stone) is set to feature in this movie.
