• The third film in the "Fantastic Beasts" series, "The Secrets of Dumbledore," premiered April 14.
• The series began in 2016 with "Fantastic Beasts and Where to Find Them."

The third "Fantastic Beasts" film, "The Secrets of Dumbledore," hit theaters on Friday, April 15. The film picks up where the series' second film, "The Crimes of Grindelwald," left off, with Albus Dumbledore enlisting his friends and allies to stop the dark wizard Grindelwald, while he himself attempts to find a way to break the blood pact that prevents him from raising a hand against his former friend.

The film sees the return of characters like Newt Scamander (Eddie Redmayne), Jacob Kowalski (Dan Fogler), Albus Dumbledore (Jude Law), and Credence Barebone (Ezra Miller).

It also introduces a new slate of characters to the series — most importantly, a new Grindelwald played by Mads Mikkelsen, who took over the role after the departure of Johnny Depp.
