It's always messy politics when an actor is out to everyone around them but not to the wider general public. It's even messier when those two signals get a little crossed and Ian McKellan outs you during the Hobbit press tour. This particular case came out of an interview with German outlet Brash. He also mentions the names of three other out gay men he's worked with: Luke Evans, Stephen Fry, and Lee Pace, as well as two of the Hobbit dwarves. That leaves it open to guessing who the other gay dwarf is, if that's your kinda game. Lee Pace, also, is less publicly out, though his sexuality has been assumed in that Zachary Quinto or Anderson Cooper way for years — namely, he hasn't said it to a reporter but he's been assumed to be dating dudes.
The subtle slip came during an interview with Brash. McKellan reflected on the question by comparing the number of gay actors in each film as a sign of the times. In , he was the only gay actor in the film franchise.
None of them are gay. Okay there was something odd about Deagol and Gollum in the film but gay I don't think so. Sam, Merry, Pippin, they married hobbit ladies and had kids.
