Interview is more reading-between-the-lines and unreliable narration when Louis is talking about his time with Lestat.

The Vampire Lestat, on the other hand, it's textual. Not traditional romance with kisses and sex but it's a romance in a vampire way and Lestat was canonically queer before he was turned into a vampire. I don't wanna spoil it by going into more details than that. Lestat and Louis are, for all intensive purpose, a couple and in love at different points throughout the timeline.

It's why people joke that Lestat babytrapped Louis with Claudia.

I haven't watched past the first episode of the show yet (it's on my list) but they definitely made the queerness far more textual than the books.

So in order of gayness, the movie had the least, the books had a vampire-level of gay and the show is queer af.
