Gay Remus Lupin is movie-canon! Well, in Prisoner of Azkaban, at least! ;)
David Thewlis says:
The funny thing when Alfonso Cuaron directed The Prisoner of Azkaban, the first film that I appear in, he had the idea that Lupin was gay and he described my character like a ‘gay junkie’ …
It’s great, when you think you spot these little clues that you think can be interpreted in a particular way … but so much better when you find out they were intentional all along!
Now i just need to find out that the Goblet of Fire movie was intentionally a great big slash-fest between Harry and Cedric … and then my joy will be complete!!
