Mads Mikkelsen has made his debut as evil wizard Gellert Grindelwald in the trailer for Fantastic Beasts: The Secrets of Dumbledore.
The Danish actor took over the role from Johnny Depp, who departed the Harry Potter prequel series after losing a British High Court battle against his ex-wife Amber Heard.
The dramatic three-minute teaser, set several years after the events of The Crimes of Grindelwald, sees Eddie Redmayne's Newt Scamander and Jude Law's Albus Dumbledore prepare to face the shadowy figure of Grindelwald in battle.
Viewers are also treated to throwback surprises from the original films, including a visit to Hogwarts and what appears to be the school's secret Room of Requirement, which was an important location in the original Potter series.
The film is due to arrive in April 2022 and will see the return of David Yates, director of the later four Harry Potter films and the first two Fantastic Beasts movies.
Fantastic Beasts 3 was originally due to begin filming in March 2020 but the coronavirus pandemic prompted Warner Bros to postpone until September.
Depp later stepped down from the role of Grindelwald after losing his high-profile libel case against the Sun newspaper.
Mikkelsen, whose credits include Bond villain Le Chiffre and Dr Hannibal Lecter in the television series Hannibal, was subsequently announced as his replacement.
