In 2007, "Harry Potter" author J K Rowling said at a fan Q&A event that she always visualised Dumbledore as gay and "fell in love with Grindelwald" in his youth.
When asked if the sequel to 2016 film, "Fantastic Beasts and Where to Find Them", will makes it clear that Dumbledore is gay, Yates said, "Not explicitly. But I think all the fans are aware of that. He had a very intense relationship with Grindelwald when they were young men. They fell in love with each other's ideas, and ideology and each other."
"Fantastic Beasts: The Crimes of Grindelwald" will be released on November 16, 2018.
