Fantastic Beasts: The Secret of Dumbledore is almost ready to unleash its first trailer on Monday, and as you would expect that means there is just enough time to squeeze in a teaser for the trailer, which gives a first look at what is sure to be one of the biggest talking points of the movie – Mads Mikkelson in the role of Gellert Grindlewald as he replaces Johnny Depp in the third movie in the franchise. The teaser shows a very brief look at Mikkelson being carried through a crowd, as well as quick shots of many returnees to the series including Eddie Redmayne, Jude Law and Ezra Miller.
