Leonardo DiCaprio and Clint Eastwood are mostly in favor of gay marriage.

DiCaprio stars as FBI Director J. Edgar Hoover in the upcoming Eastwood-directed J. Edgar.

The film will open the 25th edition of the AFI Festival in Hollywood, California on November 3 and will open nationwide six days later.

In the film, Armie Hammer, the 25-year-old co-star of last year's The Social Network, plays Clyde Tolson, Hoover's co-worker and life-long confidant.

But whether Hoover and Tolson were romantically involved, DiCaprio and Eastwood say in the October issue of men's fashion glossy GQ, is less certain.

“They were inseparable pals,” Eastwood said. “Now, whether he was gay or not is gonna be for the audience to interpret. It could have been just a great love story between two guys. Or it could have been a great love story that was also a sexual story.”

J. Edgar is “not a movie about two gay guys,” he said.

Eastwood added that he's OK with gay marriage: “These people who are making a big deal about gay marriage? I don't give a fuck about who wants to get married to anybody else! Why not?! We're making a big deal out of things we shouldn't be making a deal out of. … Just give everybody the chance to have the life they want.”

DiCaprio agreed: “That's the most infuriating thing – watching these people focus on these things. Meanwhile, there's the onset of global warming and these incredibly scary and menacing things with the future of our economy.”
