Alfonso Cuarón, in the rehearsals, without J.K. Rowling's...

Alfonso Cuarón, in the rehearsals, without J.K. Rowling's knowledge, told me that [my character] was, in fact, gay. So I'd been playing a part like a gay man for quite a long time. Until it turned out that I indeed got married to Tonks. I changed my whole performance after that. Just saw it as a phase he went through.
