Colin Farrell says the Catholic Church had it all wrong when same-sex marriage recently became legal in Ireland.

"It was really funny because one of the arguments when the vote went through was that the church came out and said, 'You know, this was a dark day for Ireland,' and all you could see was literally rainbows everywhere, posters of rainbows, T-shirts of rainbows, men and women hugging, men and men hugging, women and women hugging, and yet cut to, 'This is a dark day in the history of [Ireland],'" the True Detective star told E! News exclusively at the Maui Film Festival, where he was honored with this year's Navigator Award. "A dark day in the history of a country is internal civil conflict and war and bloodshed...It was a great day."

Farrell star has been an outspoken supporter of LGBT rights, especially so after his gay brother Eamon had to leave the country to legally marry his husband Steven.
