He said: "As far as I know, I am not a gay man. Maybe I'll have an awakening later in my life, which I'm sure will be wonderful and I'll get to explore that part of the garden, but right now I'm secluded to my area, which is wonderful, as well.
"I adore it, but a big concern was what right do I have to play this wonderful gay role?...It was about doing honor, doing justice."
Members of the queer community have taken to Twitter to express their frustration over Garfield's comments, saying they reflect a lack of understanding surrounding the issues faced by queer people.
Garfield described the play, which examines the AIDS crisis and other LGBTQ issues, as the "most fulfilling creative experience".
He said: "It's the most costly thing on the body and on the soul we've ever done personally... and I will say it's the most fulfilling creative experience I'll ever hope to have.
"I don't think it can get better than this in terms of everything.
"Communion with the audience - us all going through the same things together and how prevalent and how necessary it is to tell this story right now."
